Maximize your smartphone usage time with a ZeroLemon battery upgrade

My 7,500 mAh ZeroLemon battery upgrade is finally coming and my usage has tripled.After a few days of use, I showed everything I needed to make the most of my smartphone!You may search the internet at some point in an attempt to find ways to increase your smartphone usage time.Turn off GPS, Bluetooth and Wi-Reduce screen brightness and turn off automatically-These are some of the most common tips you\'ll find in every corner of the Internet.
Oh wait, it doesn\'t make sense because I don\'t know there is a \"corner\" on the Internet \".Let me rephrase them and you will find them if you look for them.Today, I propose an uncompromising solution.
If you\'re a heavy user, that\'s it.
I hate to limit my use to important phone calls and basic text messages.I uninstalled all the non-batteries before I equipped myself with this batteryessential apps.I have few apps except for the usual information, weather and email.
The article will also be a partial review to determine if this attachment is suitable for you.So far, ZeroLemon is the leader in affordable battery products.The reason they are able to keep prices so low is because they don\'t have physical stores.
They use authorized resellers and Amazon listings, so this is a major cost savings.At present, they have a very different product line from major smartphone manufacturers such as Apple, Samsung and LG.They also have electricity banks of their own choice.
I haven\'t tried their power bank at the moment, so I can\'t comment on their performance.I found that their battery cases range from $30 to $70.This is definitely worth considering when leading brands such as Mophie are up, or even more than $100.
I admit that this is the first ZeroLemon product I have.I later found this out while browsing YouTube and looking at reviews for other phone models.What the hell did I find?The packaging they use is actually very generic.
I haven\'t spoken to any of ZeroLemon\'s reps, so I don\'t have a full story of their packaging.I suspect ordinary packaging was used to keep it low cost.I \'ve never really used this, but it\'s always good to know the 180 day warranty support.
This must be the longest warranty period I have ever seen.It\'s always nice to know it\'s there if I need.In fact, I guess this should be a standard procedure, but I don\'t think many people know about it.
The 12-Calibration takes an initial charge of hours and 5 to 6 full discharge cycles.Regardless of the size or capacity of the battery, you should discharge completelyIn order to keep it in first class, ion batteries are often used.I\'m not saying do this every time you recharge.
Doing this too often can cause damage to your battery.That\'s why you get a warning that the battery is less than 15%.I would say do the calibration every three months.
It\'s necessary to do 12-To calibrate the battery, charge 5 to 6 discharge cycles first.When you use a battery with a much higher capacity, 100% of the 7,500 capacity is different from the 2,600 capacity on my phone.In this review, I will discuss a potential battery display issue later.
I have not experienced it, but I understand why it may cause potential problems.I heard that the battery capacity percentage display is incorrect and I believe I have found the best solution to this problem.Since the Samsung Galaxy S4 is my main phone at the moment, obviously this is the case with this model.
I stress this model because ZeroLemon makes the case from S4.Based on the case of the TPU housing, it is not very thoughtful.This is compared to the S5 and Note 4 models.
It is just a sliding cover that wraps around the edge of the phone while holding the battery.Unfortunately, it did not share the Otterbox design with the S5 and Note 4 cases.When I say the Otterbox design, I mean the plastic skeleton with the rubber shell on it.
In addition to the 180 day warranty, let\'s talk about battery maintenance.This is a topic that most people don\'t know.Most people just charge their phones when necessary.
In most cases, lithiumIon batteries can handle daily charging.Although there is a memory effect, it is so small that the battery deteriorates faster than the memory effect due to daily use.Not only does it work for the ZeroLemon battery, but you should always charge the battery with at least 5 hours of charging.
This will ensure your battery reaches full capacity.The first few times you use it, you should row it close to empty before charging.This is to calibrate the battery or to ensure that the percentage displayed on the screen marks the real capacity of the battery.
You shouldn\'t do this every time you charge your phone because it will damage your battery.If you don\'t want to do this, it should be done monthly or every 3 months.The problem I have with using the extended battery is that the percentage is not consistent with the real capacity.
This is because the 100% on my phone represents the capacity of 2,600 mAh instead of the capacity of 7,500 mAh.Manually changed the capacity of my battery.This is to better represent the battery percentage table.
Even with BMW Pro, I sometimes notice a percentage increase when using this phone.For example, I can use my phone when there is 5% left.I will turn the screen off and turn it on later and find it reports 6% now.
In addition to that, the percentage report became more accurate.It\'s not pure black, it\'s gray.Good colorNot only that, the texture is not smooth, but it feels a bit like fine sandpaper.My favorite material is that it seems to be selfhealing.
I scratched the back of the shell once with my nails and noticed these marks.Soon it disappeared like a new one.It was a bit of an accident for me, but it was definitely a good thing.I admit I don\'t like the design very much.
For me, it might be better to protect the battery.The battery is safe, but I think this case may be safer.Open the case and I haven\'t put my phone down yet, but I feel the case may fall off if I put it down.
The groove attached to the edge of the phone is not too deep, which makes me a little worried.After I took off my shell several times to show my new battery to others, my case is no longer experiencing this tight fit at the moment.That\'s not to say it\'s not comfortable, but I can still feel the loose spacing when I squeeze it hard.
The \"grill\" or opening at the bottom actually helps to redirect the sound.However, I feel that the one on the right is added for a symmetrical look and not for any practical purpose.The sound on my Samsung Galaxy S4 is not stereo so there is only one Grill to support the sound (on the left ).
Unfortunately, the S4 case is one of ZeroLemon\'s first products and they don\'t have a protective flap designed for the micro caseUSB port.This is a frustrating phenomenon because it actually exists on S5 and s6.The Galaxy S6 actually has a redirect port.
As you can see, this is a capacity of 7,500.Compared to my 2,600 mAh OEM battery, ZeroLemon is about 2.88 times biggerInterestingly, you would expect this new battery to be used more than twice as long as it was, but that\'s not always the case.
When I upload my usage statistics, I will explain this in a minute.Now you can see that this battery has NFC.If you look closely, you can identify the sensor in the picture.
This is because the white packaging is actually just paper.I\'m not sure if this is still the case, but zeromeng once called Myde-Tech.Maybe there are its own suppliers now, but the packaging is very similar.
The packaging of this paper package will never feel vulnerable or about to crack.This is a close and perfect fit and should not have any problems.I have a \"Bastex\" ID because I purchased this battery through their authorized dealer.
ZeroLemon listed their products through Amazon.Bastex is an authorized reseller to ship to Canada, so I have to buy ZeroLemon through them instead of directly.It\'s a real battery anyway.I think once I feel like most people still don\'t know about the presence of these batteries, we don\'t see fake products for this battery.
I\'m part of a couple of Android communities and no one really talks about these batteries unless you find a clue for a superuser to swap stats.ZeroLemon really highlights the initial charge maintenance.You have to stick to this, especially the first three points.
The rest of the points should be common sense.You should not stab or try to bend any lithiumion battery.Yeah, stabbed a lithium.An ion battery can cause an explosion.If you don\'t believe me, there\'s actually a video on YouTube showing the consequences.
It takes a little effort to put the battery in.I had to press my phone hard to keep this tight fit.The advantage of all this is that the battery will most likely not fall off even if the case comes off.
As stated in the instructions, it is critical to perform initial cost maintenance.This will not only adjust the percentage of the report, but also extend the battery life.In fact, I have tried a lot and I have some discoveries.
After putting the battery into the phone, turn on the phone and use it as usual.Zeromeng battery is pre-installedCharging, but depending on the time of the last charge, will experience a different degree of shelf life consumption.Of course, the percentage displayed by your phone will not be the actual \"juice\" in the battery \".
Note that even if your phone reports a battery of 1%, keep using it until it turns off itself.This is because when I put the battery in 40% for the first time, I noticed that the 15% Mark had an incredible consumption.Later, I spent about 5 hours on my last 15%.
Start charging once your phone is completely off and let it charge for at least 12 hours.I\'m using Anker 5-USB port 40-Wall charger.With Power IQ technology, I can get up to 2-Current amplifier.
This reduces my charging time compared to 1-Output charger.I will provide some suggestions for wall chargers below.Because I have a very positive experience with their products, they will be branded by Anke.
This complete charge and discharge cycle should be repeated about 6 times.After that, the battery should be fully calibrated with the smartphone as the battery percentage should be reported accurately.If the battery percentage is not reported accurately, we will discuss how to resolve this issue.
Lithium-Ion technology has made great progress, and while there is a memory effect, you can charge the battery at any time with minimal damage.In other words, your battery will wear out faster in daily use than the actual memory effect when charging.Some days I rely more on the battery, some days less on the battery.
I can charge the battery at 15% critical moments, while others may be at 60%.In my daily use so far, charging the battery is the most effective when it drops below 40%.I believe that when I charge on the 8 th or 9 th, when the battery reaches 70%, I charge the phone.
When I unplug the charging wire and start using the battery, the battery consumption of the first 20% or so is significantly faster.I lose 1% every 3 minutes I use.My usage is not considered heavy.It includes basic messaging without media streaming and web browsing.After trying this issue, I narrowed it down to 40%.
Before fully charging, dip your battery under 40%.Once you remove the phone from the socket, you will notice a rapid discharge of around 5%.It should stabilize after that.Once the discharge is stable, you will get an amazing time to use.
Now, there is a problem with inaccurate reporting percentages.This seems to be a problem for those who are notRoot oem rom.OEM represents the manufacturer of original equipment.
This is another term for the original component that comes with your phone or the component that the company officially provides you.The OEM charger is the charger that your phone has in the box.A non-The OEM charger will be the one you purchased from the Internet.
I specifically mention ROM or software on your phone.The problem with some oem rom is that the battery capacity is pre-determinedDetermined that the percentage report will be based on OEM capacity.For example, my OEM battery capacity is 2,600 mAh.
This percentage is still based on this capacity, not my new 7,500 mAh.In fact, I talked to some people about this because I didn\'t have it myself.I turned over my phone and installed CyanogenMod.
As I confirmed by installing Batter Monitor Widget Pro or BMW Pro, it seems to report the battery capacity accurately.With this Android app I can change the battery capacity manually.After this change, the percentage report of the system is indeed accurate.
For those who don\'t currently experience accurate reporting, I strongly recommend downloading the battery monitor widget Pro in the Google Play store.Manually change the battery capacity and install the secondary battery percentage monitor in the notification feed.Finally, the topic we are talking about now is performance.
I will post the summary table first.
If you would like to see the statistics of the report on the phone, I will post the picture right after that.When measuring performance, we consider two factors.The first one is standby time or on-battery time.
This is from the time you unplug the phone from the socket until the next time you plug it in.Unfortunately, this is not actually a good way to report battery performance as it does not take into account usage.The standby time is very good and you can see how long your phone can last with minimal usage.
The second measure is the screen.
on-Time or short.
This is basically how long your monitor has been on.It reflects performance better because your monitor is usually on when you use the device.It reflects the time you can actually use the device.
We will use both measures to see how much improvement we can get from the upgraded battery.These numbers are slightly biased according to the time of use measurement.Using the OEM battery, I recorded the performance data at the 15% key mark.
I didn\'t completely run out of it because it would damage the battery outside of calibration.As for ZeroLemon, it\'s still in the initial calibration phase, so I dropped it down to 1%.However, I will still stress the fact that you can get at least 3 times the amount of usage.
This is because there is an interesting phenomenon.When you have a larger battery, you tend to use your device more.This may be the case for you, but it must be for me.
I have few apps when I use the OEM battery.I uninstalled all the non-Basic applications.I limit my use to only phone calls and messages.
I rarely use my web browser because I want to use the screen on time.Of course, I was with the power bank at the time, but now I don\'t need it.With a bigger battery, I tend to use my phone more just because I can.
The format of these screenshots is to display before and after.After installing the battery upgrade, you can see the main changes in my battery usage.Should you get it?I now charge my phone every two to three days.
If you are working outdoors and can\'t access the socket easily, I highly recommend upgrading the battery.When I use an OEM battery, I use the power group for the longest time.The disadvantage of the power pack is that you have to carry an extra battery with you.
You will also have to maintain the power bank and make sure it is charged.The power bank does not provide accurate reports as they usually have 25% marks marked with 4 LED lights.If you don\'t use your phone in large quantities, or often forget to charge your phone, battery upgrades can also be beneficial to you.
If you only use messaging, I\'m sure you can use the battery for up to a week.Of course, there are also disadvantages to the battery upgrade.One of the main disadvantages is scale.I know that some people don\'t even like to use boxes on their smartphones because of the increased thickness, so you have to be ready to put up with the new size.
My suggestion, if you can, is to get it.
Android is not yet the most lightweight operating system.When your phone is constantly connected or connected to the Google Play service, it does have quite a battery drain problem.When I sometimes work long hours, I get tired of running to the store constantly or using less.
Still, I hope you find this review useful and maybe can be upgraded!
