I have gone through about 3 cycles if battery, with fast charging turned on. Battery life has not been good, especially with screen off drain. Getting about 3hrs SOT while I've heard people say theu get around 6.
So my question is how many cycles should I go through before I judge battery? And should I disable fast charging? Does fast charging damage the battery?
I have the verizon US variant, so there isn't much I can do to improve battery life without root...
Thanks
Turn fast charge off. Turn off AOD. I have an AT&T model. Helped my battery immensely....
I can go the entire day, 6am to 11pm, with average usage and have about 40% battery left. VR drains my battery like butter on a stove.

I'm also on VZW and I've had my S7 for a week. After about 3 days of poor battery life (~2hrs SOT), I turned AOD, location, BT, and NFC off, and disabled a bunch of bloatware (I posted what I did in the battery thread). That improved my SOT to over 4 hours +more standby time. I've since re-enabled BT and location and haven't noticed a difference. I left fast charge on but I use a slow charger at night, just because that's what's plugged up behind my bed.
Sorry, I don't have a source but I'm pretty sure I read something credible that said fast charging doesn't affect battery life/quality. I know that's pretty flaky, so take if with a grain of salt because plenty of other people are saying it helps.

How Is this even possible?? Do u have aod on? I need immensity help
I too have some similar questions just like @gleggie has posted
"how many cycles should I go through before I judge battery? And should I disable fast charging? Does fast charging damage the battery?"
Also how to measure battery cycles? Any credible app for the same?
Fast charge doesn't affect battery life immediately, charging your phone faster causes heating and overworking of battery, so slowly, average battery life decreases.
Slow charge when possible! (Wireless charge generally heats more than wall charge!)
... My 2 cents
My phone on fast charging, even wireless doesn't get any hotter than previous phones. My other half has a HTC One M8 for two years and still gets 5-6 hours SOT and has fast charged since day one.
I use fast wireless charging and get 6 hours SOT.
All I turned off is NFC, and my signal is usually full.

So, to slow charge a S7, do we have to turn off fast charging from the settings and then charge via the charger that came with the phone(the so called fast charger) or should we use a charger from an old phone say SIII etc.?
Does this hold true for Motorola's phone also which have turbo charging option?
Also how to measure battery cycles? Any credible app for the same?
Just turning off fast charge you do a lot good for your mobile..
One thing you can do is check battery temperature as you change charger or method. I don't know about Motorola, but maybe its battery is user replaceable... I personally don't know any app that keeps track of battery temperature

Thanks dear. I have turned off fast charge, should I now charge via the charger that came with the phone(the so called fast charger) or should we use a charger from an old phone say SIII etc.?

Thanks for replying. I wasn't able to find any battery cycle file/log in that location, quite strange. And yes I have the Exynos version. I will test your app and will get back to you.
Of the little what I have understood from various threads here is to charge the battery when it is between 20-40% to 80-90% if you want to have a good battery life. I used to do the complete opposite charge, when the battery is at say 6-7% and charge it till it is maxed. I used to do the same for my laptop, any other tip for the battery?

Hello,
Can you please elaborate issue?
-Vatsal
[
More in depth description of the problem
I Purchased a NOTE EDGE Used about 2 weeks ago, I was told the problem was a generic battery causing the phone to overheat, I bought A New battery which somewhat solved the overheating problem however upon using the phone even with a new battery I noticed there still is significant battery drain in a short time. Also When the phone is completely off the battery still drains at a fast rate, If plugged in the battery doesn't die but charges extremely slowly even with a rapid charger and rapid charge activated. Another Issue that I have is when I remove the battery the phone will not turn back on once its back inside unless plugged in and when I connect by usb to the computer it shows connected on the phone and on the computer but in programs such as Odin it doesn't show up unless I remove and re install the battery multiple times I've done all I can think of to fix this ( bought a new battery, tried re flashing the firmware, Shut off all unused apps and turned off all data Wi-Fi and Bluetooth, dimmed the screen, battery saver etc.. ) the phone drains regardless even when phone is completely powered down.

N.m. just googled it
After I updated to 6.0.1 update on my note edge , once the battery reaches 49% it just turns off , it doesn't turn on , while I put it for recharge the battery charge shows 49% and it turns on.
I have done 3 factory resets still the problem arise. I did factory reset to clear cache and to clear any errors in apps. This is my primary phone for work and I need to carry power bank all the time. Please assist
Time to change the battery. It is not about the percentage of the battery. It is more about that the voltage breaking. As it seems the battery can not longer hold its voltage due to battery age. When the voltage breaks, the device will automatically shut down to due low voltage

From what I notice is something is wrong, mine started to act weird earlier after I updated a latest ota firmware, before when I charge its take only maybe less then a hr to full charge, I did a factory reset now its take two hr to full charge, now monitor again
My battery went to hell also after this update and I just got a new one a few months ago

the only solution i see is to stop buying original battery replacment since it might not be the issue , rather slap a zerolemon 9000 mah battery on , it looks like a tank but at least the battery last lol.
Im still having trouble with mines too, injust dont understand why phone is draining battery while off and fast . You ciuld feel the heat off the phone while off...
Maybe you should try to get an extended battery pack? here's what i tried - so far so good! https://www.youtube.com/watch?v=i70xqUNoYVE
For two weeks my phone (Mate 8 L29) is discharging quickly. Initially I thought it should be because of some applications and so I uninstall the main applications running in the background like facebook.
But that did not change anything. Yesterday I formatted my phone and switched from a B180 Ephemeral rom to the stock B560 (Ephemeral B180 -> Stock B180 -> Stock B560).
The battery was behaving rather well until it reached about 60%, at which time the charge literally collapsed. The battery has gone from 60% to 27% in a few minutes. Around the 30% I saw him lose 1% every 15 seconds! So I plugged in the phone and the ascent of the load was as fast as the fall between 30 to 60%. After 60% the battery seemed to recharge at a more normal rate.
Do you think it is the battery that is physically dead and I need to replace it or can it come from a bug in the battery display?
The phone is less than a year old, but I could not use the warranty since I installed a rom.
On the screenshot you can see the battery go from 60% to 30% then go up to 60%, all in just about 30mins and without using a greedy application like a video game.

you may need to replace your battery..
when exactly did it start.
Do you always charge up your phone A's soon as it starts discharging
Do you always plug in your phone while doing heavy gaming?

It started about two weeks ago.
It happened several times to play with the phone connected. In general I expect it to be under 20% to recharge it, sometimes I charge it before if I know I have a long day without access to a power outlet.
I understand the questions very well, but it sounds quick. That a battery is so worn out in a little less than a year.
Im having the same issue and In going to replace the battery today, I'll tell you the results

Please do keep us posted in case this is a problem of Mate 8
Is it possible to make the message "your device has been unlocked" disappear ? That would allow me to try the guarantee.
I've change the battery and everything backs to normal. The battery life is huge again.

Where did you go to change the battery, was it an official change? Did you lose your warranty? How much was it?
Thanks
Also how have you guys been charging your phones? Overnight? Fast charging overnight? Or slow charging overnight?
I changed the battery myself with a youtube tutorial, very easy:
https://youtu.be/b7f8fdYz5ig
I was charging my phone overnight wit fast charging. I know fast charging overnight is useless, but the official charger only do fast charging, so no choice.
I want to change my battery myself, like janrk, but first, just out of curiosity, im going to try the sellers warranty. I try to join Huawei, they just didnt answer.
A lot of chinese website sell "Official Mate 8 battery", but im not sure they are really official. I find 7 to 9€ battery on chinese web site, 12€ on Amazon (chinese seller), 25 to 35€ with european seller. That's only for the battery, i you didnt want to change the battery yourself its between 49 to 80€.
My battery cost me 13€, and is identical to the original battery
Where do you buy it ?
I contacted the after-sales service of Huwaei. They told me that it was necessary to cut the wifi and the mobile data when the phone is in charge. And that in general it was necessary to cut the wifi and the mobile data when one does not have the use of it. I deduce that they have poorly designed these elements of the phones, and that they cause it to overheat. This should reduce the battery life.
I asked them if it was possible to have a warranty. It is possible, but for this i must accept to send the phone to them for several weeks. Since I do not wish to have no phone for several weeks I will order a battery. Their after-sales service is really useless: /

stupid thingy ...
almost same thing happend on me and i had to replace battery to solve it.
it took only 10 month to kill damn built-in battery.
i can't belive it. its just 10 month.
i never see like this.
most cheapest battery (made in china) was worked over 24 month.
I just change the battery, is actually that fixes the problem. Now I'm not sure that the battery is necessarily bad at the base. I wonder if the design of the phone does not cause an overheating of the phone that is damaging the battery prematurely.
Hello. I just noticed something weird on my TCL 10L phone. When the phone reaches 100%, it displays fully charged on my lockscreen. Though, unlocking the phone I see the phone is still charging. I see the battery bar being green with a charging bolt. It takes around 15-30 minutes until it says charged (and the bolt removed). Is this normal? I do not remember the phone doing this when I bought it around 5 months ago.
Changes in charging and especially sudden loss of capacity can indicate a battery failure.
Check for cover swelling/bulging, battery swelling is a failure, replace asap if so.
A failure this early is rare but Li's can fail at any time in their life.
Inspect jack and port for contamination. Use a known good charger and cable. Try cycling the battery until the phone shutdown then charge to 100%, repeat... to calibrate battery indicator.
Minimum start charging temp is 72F
Best start temperature is 82-90F
Never attempt to charge a Li below 40F
Keep battery temperature below about 101F when charging.
Do not use phone while charging as it will skew the charging curve.
Thanks for the reply. There is no battery loss. I can play games on this device, browse, and check apps and drain the battery in the same period I did since I got it. I actually charged it to 100% since went to sleep. 9 hours later the device was still at 100%. 1.5 hour of playing a game after that and the battery was down to 84%. The issue is really weird. I am thinking a battery calibration may help. I do not know.
P.S. I am currently using Android 10 and I do not want to switch to Android 11.
I wouldn't worry about it.
It's best not to charge to 100%.or below 30%.
Lu's like frequent midrange power cycling (40-65%).
As for 11, no way that crapware is getting on my phones....

Did you personally experience this on any device? This is the first time I saw something like this. According to some articles the phone may display wrong battery stats. So I was thinking calibration would be a solution to this issue.
So my 4a has been having fast battery drain since few months now. I remember it having very good battery life initially. However now it drains battery very fast.
This is also surprising since I keep brightness low due to me being sensitive to it.. and also keep the phone charged upto 80% capacity only as I read that it prolongs battery life.
One thing I could note is that the phone drains slower in the 80 - 100 % range if the phone gets fully charged occasionally.
Hence I have been suspecting the 'rapid' charging which is enabled by default on stock charger to be one cause.
Is there some way to enable slower charging like what happens in case of 'Adaptive charging' post 80% capacity? I hope that will lead to lesser wearing down of battery.
Don't use a compatible cable/charger and it'll change slowly. I don't think any PC I've connected to can do rapid charging, for example, and the cheap USB chargers I have definitely can't do it, only the one that came with the phone can do it.

It's more likely an app that drain your battery in background than your battery dying already. Quick charge and adaptive charge are made to not harm the battery.
Are you rooted? If yes, install Franco kernel manager app from playstore.
In first page you'll see your battery life estimation (from system) and clicking on live monitor go-to the processes tab.
Just like top cmd on Linux you'll see which process is active and how much cpu it use
For me as an exemple i realized that when I'm using YouTube music. The AdAway app goes crazy and drain my battery. And its something that's not shown on settings/battety tab.
Fast charging stresses the battery more than slow charging. That said I almost always fast charge. I expect 1-2 years of battery life on my N10+'s though.
Charging past 80% or discharging below 30% stresses the battery; Li's like frequent midrange power cycling.
Don't start charging below 72F, 82F or higher is best. High temp cut off is about 102F.
Never attempt to charge a battery colder than 40F!!!
Erratic fast charging is a sign of battery failure.
A rapid decline in capacity is another sign of a battery failure.
Any rear cover bulging ie battery swelling is a failure, replace asap.
Once a battery is below 80% of it's original capacity it's degraded and has reached the end of its service life, replace it.
Degraded Li's are more likely to fail which can easily destroy the phone.
If the phone is used heavily or is 2-3 years old, probably time to replace the battery. Just do it.
On most phones the cost is low.

Frankly don't have that much usage of my phone. Will give sometime to observing with non rapid charging. Will give this a try if that still persists.

If it seems to work better... I don't see any difference on my N10+'s though. Run times are the same slow/fast charging.
Keep a close eye on it as erratic fast charging is a sign of battery failure... I have seen that
