Swapping battery

Hi.
I recently purchased a new battery since the old one is kind of broken.
However it didn't really increase battery life at all. In fact it now shuts down at 35%.
How do I make sure it actually makes use of the whole new battery?

Is the battery from Samsung?

Yes it is.

You must calibrate the battery.
To do it you must be rooted.
Advanced method;
Use a root explorer and go to /data/system. Delete "batterystats.bin" file . Then drain all the battery and charge it while phone is off and unplug the cable whem it says full.. Thats all.
Also there is much easier way to do it if you want. Download battery calibrater app from google play and use it! BUT in any of these methods,you must be rooted.
After doing this it must be normal.Also flashing stock rom and non rooted musn't be problem

This is not true.
http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
This misconception must stop being spread.
Though you're right about the charging bit, op should discharge until it's completely dead, then fully charge it and let it run out, repeat the process.

adytum is right. The phone doesn't need to be rooted. Rooted you can destroy the phones battery statistic file at once but you don't need to. Android permanently learns about your battery (high / low voltage) when charging and discharging.
Have some patience, give your new battery some full charges / discharges and everything should be OK.

I'm going to start working on this then.
Thanks alot !
I was already afraid my whole SGS was broken.
edit: But doesn't draining the battery completely lower its lifetime?

Difficult question - doing big researches will lead to different answers.
The only thing for sure is that completely drained or somehow even completely full batteries will age faster because of electrochemical reactions. Completely drained is worst case, of course.
A common recommendation of the industrie is to store an unused battery charged at about 60-70% and then put it away in some cold storage. That is because even LiIo-batteries suffer self-discharge of about 5-10% per month so it could avoid both stressfull states (0% / 100%) for a long time.
Your phone will never physically drain the battery completely, but will shut down itself before damage is done (don't know if this limit/border could be tweaked, but with StockROMs you should be save). Although it might say 0% there is still some energy left. So it wouldn't hurt to "drain your battery completely" down to 0% a few time if you don't forget to charge it afterwards.
As Android stores the min and max voltage of your battery your really should do complete cycles if you want Android to get your battery statistics right. You even have to do this if you killed Androids battery file on a rooted phone.
Much more damage will be done by keeping the battery at high temperatures, e.g. playing heavy games

I've been doing what has been suggested, however my phone keeps turning off between 30-40%.
Is there any way to solve this?

well u have purchased a junk battery (its rare but sometimes happens, give it back and get ur money back)
i myself use a powercell 1800mAh battery and it pretty much doubled my phones battery life (u could try it)

If you already have a rooted phone and no patience (no experience myself on this matter with ICS or JB), then you could use app "BatteryCalibration" to remove batterystats.bin file as was said in one of the initial postings.

if u use cm10 you can also enter cwm and whipe battery stats, i think under advanced

Anyone returning the ZF2?

I was wondering if anyone is returning their phone after getting the US version, and having some issues with it, im thinking of sending it back to NewEgg.

What's the issues that you are facing?

If you've already done a reset, I think you should return yours. There should be no lag, Antutu should be around 48000, and screen on time at least 4 hours.

I'm facing some issue with my AZP 2 4GB Version.
1. Sim 1 4G Sim network goes in every mins. If i use 3G or 2G sim in Sim 1 slot it works fine. with 4G sim it gives an error as well Unfortunately, the process com.phone has stopped. Did factor reset. I was on firmware 2.15 when i did that. Yesterday i has=d upgraded to V2.17. need to test again with 4G sim. Is it the same or still had an isuse. If yes than i'll return the phone with cash back.
2. Circle Flip cover does not work. I have purchased it in Rs. 499 and after applying the cover, nothing happens.
3. 2 to 3 times a day i have an error Unfortunately, the process com.android.systemui has stopped
What should i do??

Whats the solution to battery life and overheating during regular use (not on the charger)?

You realize your issues with heat build during charging are because of the fast-charge technology, right? Totally normal, as a ton of power is flowing into the phone. You can always use a slow charger to charge the phone while in use. You shouldn't have any heat build up during use when not also charging. I know I don't. The hottest the phone gets is slightly warm.

For overheating, use a different adapter if you have the 1.8 GHz version. Battery life, just get a third party battery saver and turn on airplane mode. That will save you a ton of battery. I did it for mine and the phone last from 6 A.M to 10 P.M.

Very dependent on ambient temperatures as well.

Anandtech has confirmed that the panel in the ZF2 is inefficient compared to competitors, so not much can be done about that aspect. Their analysis of the phone is in depth, as are their other reviews.
I would like to return mine because the battery is performing right under the Optimus G I owned. With 3000mAh I was looking forward to battery comparable to the G2. If the next OTA improves battery, then I'll keep the Asus.
"I'd Totally Hug You, If That Was Something I Did"

Dang, so the bad battery is a hardware related (screen tech) issue based on that review.

Yeah. The people from Anandtech are pretty good at evaluating devices. Also this would explain why the battery drains rapidly during use & barely when inactive. Battery life is very important to me, so a phone with a removable battery might be best.

One thing to keep in mind, is that though the display uses a lot of power, the Intel chip itself seems very efficient. Not only does it sleep well, but as is shown in the PCMark testing on the Anand website, it uses its power very efficiently. Thus, though the phone's maximum display on time is much lower than the other phones, its practical usage time is fairly similar. I get around 5 hours screen on time with 1-2 days of sleep time.

For me getting even 4hrs is requiring me to disable apps, use greenify to kill background apps, and use min brightness. I tried factory resets, so doing those over and over isn't improving my battery. Honestly I just want a new phone with the battery life of my G2, since development is slowing down for it.

Now hold on guys. Even if this phone has some battery issues, we can all still say that this phone is very acceptable. Right?

Besides battery I don't have any performance complaints. This is the main aspect I complain about. I'm still impressed that mine rarely warms up, signal is better than my G2, the battery cover has the brushed look like my Asus laptop, and so on.

Is this battery consumption normal?

Hi all,
I just come with this Screenshots to know your opinion on the consumption of my s5. Honestly Im jealous of those people getting 4,5hours of SOT in a full charge. I believe I can barely achieve 2h. My phone is rooted, de bloated with smart debloater and uses Greenify (which has not provided me a noticeable gain).
I've seen a very big drain just after plugging off the phone (like 5 or 6%) in two hours without using it. Also everything I unlock the phone the drain is very fast. So idle state seems no to be the cause
What are your thoughts? Thanks in advance.
By the way, while writing this post I've lost 5% of charge.

Need a new battery I think and with the battery you gotta keep it cool, don't charge you phone and use it when its under 20 ℅. And the hotter the battery gets the faster it will discharge and if your charging at the same time the CPU will work harder to charge the battery and do whatever you want to do with your phone making it a double whammy wearing out your battery much faster than normal. You not supposed to let our batteries to go below 20 %. Well you can but don't use it at the same time your charging.

Thank you very much for your information. Any suggestion about a new battery? I've seen this one.
I've just plugged off from 100% and I got a battery drain of 5% just by speaking 15 minutes (no hand-free). I think it's a very big battery drain for just a small talk. I think that confirm your hypothesis of the wasted battery.
Is there any way to know the real capacity of the battery I currently have? It is just to know how far it is from its original performance.

I've checked on Go Power Master app and it claims 2520 (at 90%) mah in my battery. Is this confident? If so, I shouldn't expect a big improvement buying a new battery. What about using other roms or making a factory reset?.

How old is your battery? Mah rating and the rate it discharges are different you can discharge 2600 mah batter in an hour or 3 days depending on use and environment and conditions. Like I said before the hotter your battery gets the faster the disharge go same with the cpu the hotter it gets the more power it demands from the battery. And if your battery get under 20% fast charging comes. Into play as well which is bad for the battery as well.
If your dropping off that fast I think is a defective battery or over clocked cpu settings. My s5 did he same till I bought a new battery I last 8-12 hours of heavy use now compared to 4 hours. With a new battery I suggest a higher capacity but same dimensions as the old one they can be expensive but a bigger battery will damage your phone over time.
I have a 5600mah battery now by 5he way.

Oh my power app tells me I have 2520 too but I really dont....heh
---------- Post added at 03:12 PM ---------- Previous post was at 02:46 PM ----------
Oh that battery looks OK I can't read the language lol just make sure its not refurbished or used and check out if u can refund it or not lol

My battery is from October 2015. It's the original one that came with the phone

Here is last report:
Despite performance is not the worst, do you think the difference with a new one is very big?

Back in my S3 Mini days I had to change the battery and the difference was huge for it. A year ago I replaced my S5's battery for the first time (I own my black beauty since february 2015) and I remember that I saw an improvement in battery life and in performance a bit as well.
A trick: take out your battery and put it on a flat surface (table or whatever) and try to spin it. If it spins freely, buy new one for sure.
I'd advise you to also update from KitKat to Marshmallow as that made my phone brand new but I see you're on 6.0.1 already so nevermind
I myself lose the first ~10% of my charge in one hour or even less...while not doing literally anything with my screen off. So yeah, maybe it's gonna be time for another replacement in a few months
By the way I tried Greenify today. The drain was far worse than when I didn't have it installed lol. Android Marshmallow is finally that one guy who's capable of handling himself alone without helpers like Greenify so try without it, it eats up your CPU anyway (as minimal as it can be, it still does).
With 3G always enabled I can get between 3 and 4 hours of screen on time (no games ofcourse) and around, idk, 10 hours total time until it hits below 10% and asks for some juice.
This^ was simply impossible with android 4.4.2 on the same phone so 6.0.1 really impressed me a lot as I had awful memories of Lollipop (that's why I didn't update for so long actually).
To sum up: try all the software ways of extending your battery life - with/without Greenify, uninstall/disable/optimise certain apps like Facebook and Spotify (says they slow down my phone), change ROMs, change kernels, change settings and if nothing works get a new battery.
PS: When Samsung go back on track and put a removable battery + all old features in a new flagship, I'm switching to that (S9, S10, SX, whatever xd). Newer phones got water cooling (~30 degrees while gaming, S5 gets 36-40C).

Thank you very much for your long answer. Honestly I don't trust too much battery savers. I've tried in the past many of them with no visible results. In fact greenify has never shown me any benefit. Notwithstanding, in this specific case, I've seen that hibernating "mi fit" (from xiaomi) I can appreciate a considerable improvement (5-10% of gain). I own a mi band and apart from keeping Bluetooth on (which seems not to be a big drainer) mi fit abuses of this connection. In fact "tools & mi band" seems to be more energy efficient with the connection to the mi band.
In any case I'll order a new one as it is not normal to have the drain for 100 to 90 being off and idle

I've changed old battery for a new one and I haven't seen any considerable improvement. After it, I've done a factory reset and a battery calibration (using the app on the store that requires root) and nothing... Any suggestion? I have the feeling that new battery is OK but somehow my phone is unable to take advantage of its performance...

If it gets fixed after firmware reinstall then it's a software bug. If it gets fixed after changing the battery then it's a hardware bug. If it doesn't get fixed after trying both things then it's black magic :s
Also try to clear dalvik-cache and cache and do factory reset before and after flashing.

Sorry for the delay in replaying but I've made several attempts with not specially good results.
Now I'm getting 24 hours battery with 2h SOC for WhatsApp and browsing. Furthermore, I use Bluetooth for the miband.
The battery drop from 100 to 90 still remains. Maybe it's smoother but significant.
I've changed battery, changed roms (several times wiping everything). I've tried battery calibration app from rooted devices. I've tried the calibration procedure for non root devices (here I think I've obtained a little bit of improvement) but in general I have the feeling my phone is not detecting well the capacity of the battery (either new or old). Any tip? Advice?. Could it be the charging circuit? Can it be fixed? Should I keep doing calibrations more often to see if I grasp more capacity little by little?
Thanks for your time and help

Poor battery no matter which rom

I've been using several different 7.1.2 roms and battery life has been atrocious. I use wingoku 4.1.
I pair my smart watch to it but even when I use wifi (no bt) its bad, draining quickly, last checked about 22% per hr. Even with screen off listening to podcasts it still will drop a lot more than it used to.
I really don't have much in terms of stats. Honestly I don't obsess much about it normally but now its noticable.
Aside from suggesting another rom & kernel, would I benefit from formatting data and starting over?

Install accubattery and run it though a few charge cycles, it will be able to tell you the life left in your battery, it's possible that you have the same issue many of us have had with a degradation of the battery.

Yea. Thats my biggest fear. Ive replaced small parts before but my eyesight isn't as good as it used to be so Im afraid I might mess it up. Plus I'll need to buy a heat gun.
I'll be more than a little pissed if the battery's shot. This phone is barely 14 months old. Either give us a decent battery or make it replaceable.
Thanks for the info btw. I just installed the app.

Update--Im switching things up a bit. Recently I made some changes and this time I flashed a new rom without some of those changes.
1. I had switched from Action 3 to Nova
*HIGHLY doubt nova is eating up my battery so Im still using it BUT I did remove a widget that has weather. Since I keep phone on device only location, I think theres a chance its always trying to find my locale and consuming battery.
2. I didn't add a gov profile yet.
3. This is the first time in about 4 or 5 rom flashes I didnt flash CTT Mod.
* Again I doubt this is causing battery issues but Im gonna hold off flashing it. No throttling thus far.
As suggested Ill be monitoring with accubattery for a few cycles. But been using my phone about 90 mins this morning (at least 90% of that time actively using with screen on) and I've lost 13%--a huge improvement from yesterday.

Accubattery for the proof. New battery for the fix. You could always buy online and have it installed locally. Read up on where to score a good replacement battery, rather than another dud.

Its not really giving me much info yet. Because of my schedule throughout the day Ive charged periodically so I have enough juice in case I need it. Do I need to let it run lower to get an accurate reading?

Best to let it run below 20% at least and then fully charge until the APP tells you the battery is full- not your phone. Don't unplug until Accubattery says it is full. What you will observe is that the phone will continue to charge for 45 minutes to an hour past when the phone itself is reporting 100%. You will find the estimated capacity under the Health tab. Once or twice below 20% is enough to get a close approximation. After that it will move a couple percent max. You will know soon enough.

Best to let it run below 20% at least and then fully charge until the APP tells you the battery is full- not your phone. Don't unplug until Accubattery says it is full. What you will observe is that the phone will continue to charge for 45 minutes to an hour past when the phone itself is reporting 100%. You will find the estimated capacity under the Health tab. Once or twice below 20% is enough to get a close approximation. After that it will move a couple percent max. You will know soon enough.

Well it turns out my battery is in need of replacing.
I let it run down like you said. I was going to go further down but once it hit 20% my phone turned off. I plugged it in, opened accubattery and it said 46% under health.
But I just checked again after charging to 100% and it now says 63% (2182 mAh total capacity).
I checked my imei on the Huawei site and my phone is 3 days out of warranty. Im hoping to get them to fix it.

Well sorry to hear that. Good luck to you on the RMA route. If not, the Cameron Sino brand replacement is a bit more expensive but includes a working battery temperature sensor. It will make your phone like new. Note in the thread I referenced above, some parts may get scratched/cracked depending on the skill of the repair person. They aren't expensive so it you are intending to keep the 6P for a while longer, it may be worth it to buy those just in case.

Thanks for the support! I checked that thread and didn't see specific parts (inexpensive ones you referenced) If they're listed Ill look again. It doesn't seem too daunting. I was able to replace the screen on my son's WiU controller. Those were very tiny parts and YES--I did snap off a clip, however I was able to fudge it and it's still working about a year later.
Far as RMA, does anyone know if they replace it with the same crappy stock battery? From my perspective this seems like a clear case where a recall is in order.
But if its the same battery, Im just setting myself up for the same problems 8 to 12 months from now. Even if I buy a new phone Id still want to sell this one and thats not as easy with a crap battery. Plus theyd have my phone for x days so Id need to find a temp phone in the meantime.
Don't mean to jabber on...this sucks.
Oh yeah...cuz it was after hours I sent an email to support last night. Do you think Ill get a response? Or should I just call when I have time to be on hold?

Spoke to a clone at Huawei then asked to speak to the clone's supervisor (wasn't sure if clones had supervisors--they do. But the programming is identical.) Long frustrating phone call and they aren't going to replace my battery because its out of warranty...by 4 f#@&ing days!
I told them they lost a customer for life and I was being 100% sincere. How could I ever buy from people who thinks it ok to sell defective crap, know about it, then do nothing to make things right?
I'm gonna replace the battery on my own. Whether things go good or terrible, one thing is certain--itll be the last time I ever replace anything on any product made by Huawei.

Tab S2 8.0 keeps rebooting.

Hi all. I bought a tab s2 for my step-dad this past Christmas and it keep rebooting once reach like 15-20% battery. One point, it got stuck on Samsung logo. I had to hard reset. I ended up exchanging that tablet with Amazon. Now the exchange tablet is doing the exact same thing. What are the odds of this happening again? Do these suffer from random reboots? I don't want to exchange again and it happens for a third time.
The tablet went to 0% charge. And it didn't turn on since then. It's currently on Samsung logo. I have older samsung tablets. And this never happens.

I've been using my SM-T715 for the last 1.5 years and can't remember a single reboot irrespective of battery level.
For others to help, consider sharing your model number and firmware being used. :angel:

You can find those exact numbers somewhere in settings.

i know. i dont have the tablet with me at the moment. but i cant check that anyways. since the tablet wont reboot..

So I sent the tablet in for repair.. they swapped the motherboard.. two days later.. it does the same thing.. so bizarre.. once it reaches zero.. turns off it wont turn back on.. stays on samsung logo screen...

I'm taking it to samsung directly tomorrow. theres a repair center around me. They said they replaced the board but I don't think they did.

I don't think the board is the problem, more likely the battery is the culprit.

hm.. maybe.. its just weird it charges from 0 to 100% with no problem.. but then it doesnt boot. stays on samsung logo

Wth is going on with this tablet. I finally got it replaced by Samsung. New one is doing the exact same thing. Tablet is been used lightly. The tablet died to 0%. Now it doesn't want to turn on again. Crap is annoying.

Going to restore and install one app at a time and see if maybe it's an app that causing it. It has to be.

I have the same issue with S2 9.7". It randomly reboots with more chance the lower the battery is. Mostly zero chance above 50% then with around under 30% it happens way more often, especially when you install/update apps. So I guess the entire Tab S2 line has a battery issue, maybe a too low voltage over time, resulting in CPU/flash memory becoming instable of too low voltage. Mine was actually just 2 weeks old after showing the issue. Instead of swapping the battery, the repair service mostly will just swap the motherboard, which will not solve this issue.

Thought I had a fix - but I just got a reboot

Hey everyone. Just wanted to tell you i got the exact same problem in my T713. It's most certainly a spike on battery usage and the inability of the battery to keep up due to degradation, as this problem presents when I'm trying to do intensive tasks like watching videos on youtube or entering many apps in a short timespan.
My personal fix was to underclock the CPU maximum frequency using smartpack from 1804Mhz down to 1612Mhz. Obviously you need to root your device for this fix. Once i did this the rate of random reboots diminished substantially while minimally impacting performance. I know its not a perfect solution, but if you use your tablets just lightly, this might certainly work. Changing the CPU governor to some conservative mode might also do.
Hope this helps everyone.

Seems to work for me too on my T719. For the first time in ages I was able to use my tablet until it shut down itself because the battery was too low, usually it started rebooting at 35-40% of battery.
Thank you.

I'd like to try the underclocking on my T813, could you please explain a bit more what you've done?
Thanks!

I just installed SmartPack-Kernel Manager (ROOT) from the playstore. Open the app and click the hamburger on the top left. Go to CPU and change the Maximum Frequency. Swipe over the Apply on boot.
I turned mine down to 1382 and I can make it to about 25% before it starts to reboot. We will see if that is good enough for the kids.

Thanks for sharing, will try this too!
I have had the tab sent back under waranty but the problem returned.
At first manifesting itself using a boating navigation (navionics) but this morning opening the play store also rebooted.
After recharging when making a backup AND trying above solution at 40% battery I could at least start navionics, which was hard before.
Edit:
Rebooted below 23%, changed cpu settings but forgot to reboot to apply.
Now at 11% and navigation still working.
Edit2:
For the first time in I think over a year I have been able to use the tablet for hours on end!

Thanks a lot, it did indeed help. I set the frequencies using Kernel Adiutor and for the first time in weeks I was able to use the tablet below 50% battery.
