Before I used this code, the battery life was very good because my phone is new i bought it before one week only! it takes 2 days of full conection and use to get it from 100% to 20%!!!
after using this code of *#0228# the battery come down very soon... normal using not much it takes less than one day to fall down from 100% to 5% and without full using! and believe me, when I go to sleep and I put the phone in standby without Always on display in the morning I found 8 to 10% are gone!!!

No idea what you did.
I'm not going to Google search this down... you should have known what the code was before using it.

Try this again, follow the directions but there's no guarantee this person knows what they're doing.

You alter a hidden file. You might be able to access it with ADB, don't know. Or what to punch in if you can.
Not even sure a factory reset would fix this if it's not on the userdata partition.
Hopefully someone here that knows will help you.

Nexus S i9020A - Battery Drain (Both ICS and GB) really need help

I am very sorry to open a new thread about battery drain that has been discussed so many times but I am really desperate.
I recently purchased a second hand Nexus S i9020A (unlocked AT&T version) from swappa. (Website that sells only android phones) and I am getting terrible battery life no matter what I try.
The phone is rooted and have tried several ICS roms and all have terrible battery life about 6-7 hours when the phone is on idle for most of the time.
I then installed CM7 as I read that ICS has some battery drain issues, but I still get really bad battery life 6.5-7.5 hours again the phone is on idle for most of the time.
I also tried several kernels.
I tried disabling the WIFI, GPS etc this did not help.
The phone came with two batteries an Anker Battery and the Samsung battery. I sent Anker an email asking them about the battery life, they told me to let the battery discharge to around 10% and recharge to 100% a couple of times. I did this twice, but no improvement in the battery life I was about to do it a third time when I fell asleep the battery must have drained completely and now that battery seems to no longer be working.
I thought maybe I am really unlucky and I got two bad batteries, so I purchased a new RND Battery from Amazon as I thought maybe there were some problems with the Anker. Turned off the phone let it charge for 7.5 hours, but the battery meter still showed that it was not fully charged, but the instructions said to charge for at least 5-6 hours, so I turned on and unfortunately I have the same battery drain.
I have installed a Battery Calibration app from the Android Market to see what the reading was and when the phone read 100% charge it was a little over 4,000 mV . I am not sure if this is what it is supposed to be, maybe one of you can let me know.
In addition I have wiped the battery stats from from the bootloader a few times after I have fully charged the battery and even factory reset the phone but this made no difference.
Last night I even flashed a new radio I went from I9020AUCKF1 to KB3 but this also made no difference. I have been struggling with this problem for about a week with no improvement what so ever.
I read that its bad to completely discharge Li-on batteries, so before I left home to go out, I turned off the phone so that the battery would not discharge, when I arrived home a few hours later the battery was dead even though the phone was turned off. (this was the original Samsung battery not the new battery I purchased, I did not try this with the new battery as yet)
I checked the battery usage and compared it to a Galaxy S2 to see what was using up the battery and the OS and Screen usage % seems to be comparable amount to the GS2.
I also tried a few of the Governors that are included with CM7 and also used the wheatly Governor when I was on ICS, but it made no difference.
Can any one help me? Is there something wrong with the phone? I purchased this as a present for someone who really wanted an iPhone because I could not afford an unlocked iPhone and they are really disappointed by this. I know this may be an isolated case, but I always assured the person that the android phone can do everything the iPhone can do, but not I feel like such a fool.
Can this be fixed? I purchased this when I was in the US but now I am away so returning it would be a problem. Is there a way to check if there is something wrong with the phone itself that's causing the battery to drain at such a fast rate?
Any one that can help me I would really appreciate it and be very thankful, I know there are other topics that deal with battery issues, but I have been researching this for about a week and tried everything I can, I didn't just start a new thread without trying.
The screenshot below shows a high display usage because I was using the phone to try to troubleshoot normally android system uses the most and display is closer to 7% but the uptime is the same. Even though it says 3h 51 mins at 48% in the screenshot the battery seems to discharge faster as it percentage goes down.
Can you enter this code and check for battery information:
*#*#4636#*#*
You can check the battery health and temperature. It might give you some insights.
Do you have good reception? Is it constantly trying to connect to 3G networks? Can you check apps which might be trying to connect to Internet all the time? Do you have this problem once you flash a clean rom (or maybe it starts after installing apps)? Have you tried stock ROM?

I've read about this in other threads... not sure if I've already tried it... ull need to do a factory reset to wipe all data and battery calibrations. Once u reset... flash Evilistos ICS rom 4.0.4 and use the Air Kernel 3.0 .... flash the Tweaked Nexus Boot Animation (looks really nice but you don't need too lol) and that should do it... =]

Hi Oogway first of all thanks a whole lot for your response.
I dialed the number and got the following
Battery Status : Discharging
Power Plug : Unplugged
Battery Level : 100
Battery Scale : 100
Battery health : Good
Battery Voltage : 4096 mV
Battery Temp : 34.0 C
Battery Technology : Li-ion
Time since boot : 9:58
Just finished charging it again.
I have good reception, but I have no data plan on this phone so it isn't using any 3G, actually I don't even have 3G in my country :|
I have no apps installed and the problems still happen even with a clean install. Before the person shipped the phone to me I asked them to install the stock rom and when I got it the problem was present, since then I tried different roms but to no avail so far.
Thanks very much for your time and effort in offering possible solutions, I am grateful for your help.

Its not a new phone its a used phone, but the seller has agreed to refund me if needed, the problem though is that I bought the phone in the US but I am not in the US now, if I return it to him he may be charged taxes etc.
I returned the phone and radio to stock, but it seems the issue is still present. Any more ideas?

Tried this, but no difference.
Did you buy through Ebay? Perhaps you can print out your receipt and get a warranty repair through Samsung. That's what i did when i deleted my imei. Cost me nothing except postage.

I have abyssmal battery as well with my used i9020t. Although I have only used various ICS so far and don't know how used the battery is.
At night I put it to airplane mode and closed running apps. In the morning the phone feels warm and battery drained drastically, which makes no sense.
I just got an Anker battery as well and will try some Gingerbread rom. For now I'm using Franco kernal and undervolting by 50mV which help a bit, but not much.

Hi Bedalus, I bought it on swappa. I bought a few phones there before without any problems. I have a paypal receipt from swappa, maybe I can email samsung and find out if they can repair or not. I honestly think its a hardware issue now. Because the battery still drains even when the phone is off. I flashed several radios and roms, wiped battery stats, changed battery, wipe data and factory reset and its all the same.
My issue though is that I am not in the US and the phone was purchased from the US so return may be a problem as well as shipping to Samsung, but I will email them to find out more.
But thanks for your suggestion Bedalus, really appreciate it.

Hi Ekasol, does your battery drain even when the phone is off like mine? How much battery life do you typically get? I get around 6 hours. Just to let you know that I did flash the stock ROM on the phone but it made no difference to me.
Mine is the AT&T version, I got the roms here .. http://forum.xda-developers.com/showthread.php?t=1445621
But you can get the roms for yours here http://forum.xda-developers.com/showthread.php?t=1063664 in case you have not found the original roms yet. Best of luck, I hope at least one of us is able to get the phone working or repaired.

Bedalus, before I contact Samsung, do you know if rooting and installing custom roms void the warranty?
Technically yes. However, if you wipe, install a stock rom and bootloader and lock the bootloader afterward, they have no way to tell.
Thanks Harbb
Can you try this Gingerbread rom NSCollab anyway, I know you said you tried GB already. I don't have time to test with full battery yet, but Gingerbread seem to retain battery life pretty well.
If you still have time, I would say save yourself the hassle and return it, it sounded like hardware issue. And buy the person an iPhone instead. If he/she is not tech savvy it is pointless and will just give the person a difficult time. I do not have an iPhone, but I have to do iPhone tech support for my co-workers, Android would just be a nightmare.
Also if the person don't mind going with T-Mobile, see if you can return it and get a Galaxy S 4G. It is one of my favorite phone. No LED flash and ICS (yet), but you get microSD slot and HSPA+ 21Mbps (cheaper plans too). And best of all the Valhalla roms.
Tried NSCollab, battery drain seems to be a little worse with this ROM. The reason I did not purchase the iphone is because of the cost, I got this for around $260. Thanks for the suggestions though, I will consider them, but so far it looks like this phone has some hardware problems.

Battery problem

Hello, i'm a newbie to xda developers... I had some problems with my Sensation... I am really a newb to those stuff since i never rooted a phone... The problem with my phone is that the battery doesn't slowly drain... I let it to charge for like 5 hours to get to full 100% and then from 100% it goes to 60% in like 10-20 minutes while i use it ... Other times the battery shows to have more power and other times it straightly goes to 40% from 100%... It drains so quickly i can't even go outside with my phone since its battery gets empty... Sometimes, even if the phone is 60% it randomly shuts down and have to restart it for like 5 times to get it work for at least 10 minutes. Might it be the battery? I tried going to recovery mode but i get the red triangle with an exclamation sign in it... Any reply is appreciated, thanks!
Maybe your battery is rubbish and you should just buy another one.
Although is one thing you should try first, recalibrate your battery.
What all these methods amount to is how to teach your phone about battery performance. Calibration is about enabling your phone to provide accurate estimates of remaining battery charge and will not, in and of itself extend the usage you get on a single charge (though it may possibly prevent the phone going into power save modes prematurely, wrongly believing the battery to be lower on power than it is).
The phone stores information about the battery in a file called batterystats.bin which sits in /data/system. Normally you won't have direct access to that file, but you could find it with an app such as root explorer, which allows complete access to the phone's file system.
When you install a new ROM, or a new battery, or perhaps periodically as the battery ages and performs differently, you need to get a new set of battery performance statistics.
By charging the phone to 100% you are starting at the known maximum for the battery. At this point, the batterystats.bin file needs to be deleted, which forces the phone to recreate the file from scratch, using the information it is about to collect. It doesn't matter what method you use, battery calibration app, or from within recovery - they all do the same thing and delete this file.
The phone is then allowed to drain fully. This gives the other end of the scale, the known minimum. The phone then has then experienced the full charge/discharge cycle of the battery and stored that performance information in a new version of the batterystats.bin file.
Now that the information has been saved, the phone will (hopefully) be able to provide accurate estimates of the battery charge level, regardless of how much of the battery charge you use before reconnecting the charger.
If you don't have root access you can download an app from the market called "Battery Calibration". It does the same thing, deletes the batterystats.bin.

Thank you for your time. You explained really well and i appreciate that... So, to use the calibration apps i need to have root access... should i search a tutorial on that or is there one on the forums? If the calibration can't fix it, should i get another battery? Thank you again! Maybe i should try to buy a new battery first... is rooting safe? can i get back to my old firmware?

Well, yes I guess you should root your phone first, but I'm not sure
A guide on how to root your Sensation can be found here .You should only do the steps 1-3.
If you don't want to root there is another method somebody wrote (I haven't tested it personally)
1. Turn off your phone.
2. Fully Charge.
3. When getting 100% signal, unplug quickly.
4. Pull off the battery and put it anywhere.
5. Wait for 180 seconds minimum
6. Put back the battery on the right side.
7. Turn on the phone.
Than you should be OK:good:
If you get the same result after "battery calibration" I suggest you buy another battery.
Hit THANKS if I helped you
Hello, i have two more question related to this thread... Is there a way to calibrate my battery without root access? And will buying a new battery surely fix my problem? Thanks again!
You might be able to get a calibration application in the playstore. However most I've seen require root access. But look, they're might be some without root requirement. As for your second question. Nothing is ever 100% guarantee that it will solve the issue. These are suggestions based on the information you provided regarding your issue . How can anyone be 100% certain that will solve your issue. It's defiantly a possibility it will solve the problem but no, for 100% certainty, I don't think anyone can say that. It's defiantly worth a try ! Then you can see if getting the battery solved the problem. I hope it does fix your issue and wish you the best .like I said, no one can be 100% sure but it's defiantly worth trying!Sent from my HTC Sensation 4G using xda premium
Everything said in this topic is PURE NONSENSE. It was even featured on the front page that wiping the battery stats DOES NOT DO ANYTHING. See this article for more information > http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
The only thing you CAN do is charge your battery to 100%, and let it drain to 0%.
Aparently, after i cleaned my battery contacts it DOESNT jump to random values... drains continously.. SO i think the problem is fixed... atleast for a while! I'm new using a smartphone and the battery is a little 2 weak as i was used to my other non-smartphones... I think that's the battery life a 1520AMH can offer me on a sensation! The uptime for it was 6 hours from 100%... thats really weak ( i used the web and games).

Nexus 5 sudden crash

Running kitkat, battery recently replaced. all good for a month.
Yesterday the phone suddenly switched off , i switched it on again and the battery had jumped down about 40%.
It crashed again but then remained stable for the rest of the day.
Tonight (at 50% battery remaining) i got a sudden warning "6% battery remaining" and it crashed again, i switched on again and the battery went back to normal , around 40%, stable since.
Any ideas or is the phone on the way out ?
Did you buy an official N5 battery? It looks like a faulty battery...
This is the one i ordered

Phone seems ok today so far, would wiping the cache be worth a try ?

It can't do any harm but it won't help in this situation.
Try the following:
1. Let the battery go to 5% then charge your device to 100%
2. Disconnect the cable
3. Reconnect it and check if the battery level is at 100%. If not keep charging. If 100% disconnect and reboot. Then reconnect until 100%
These steps worked for some users (even if steps 1 & 2 should be enough IMHO).
Moreover you can try to remove apps or flash the factory images to check if the problem persists. If nothing works then your last attempt is to send it back to ReplaceBase.
thanks for taking the time to reply, will try your suggestions,
Just had another strange battery drain, captured it on this screenshot.
You can see battery just takes a sudden dive and recovers somewhat.

I have just read a nice thread about massive battery drain. Check this out.
His explanations fit with your battery stats.
Thanks for that, will have a browse, but would it explain my phone suddenly dying at 50% ?

I guess. Anyway you should follow the above steps and clean up your device by removing useless apps/features. Finally flashing factory images is sometimes a good thing to start from scratch.
Thanks again
I just tried your first suggestion, charged till 100% then disconnect, it immediately dropped to 99% so i recharged to 100%
Then disconnected and rebooted, weirdly when the phone rebooted it said the battery was now at 19% ,
Back on charge again.
Ugh.... Good luck but I would bet on a faulty battery. You'll probably have to send it back if you can use the warranty.
Did you have the same issue after receiving the new battery? Did you change several things of your setup (kernel, new apps...)?
Going from 100% to 19% can't be explained by the above thread. IMO no apps, no kernel, no software can explain this drop. Some folks say that it can also be caused by the motherboard...
Replacebase have promised to send me out a new battery , they too think its likely a dodgy battery, top customer service so far, hopefully it wont take too long to arrive.
I didnt change anything on my phone, perhaps updated some apps , its stock Kitkat,,, meanwhile Is there any way to check the health of the motherboard ? i don't like the sound of that.

Without profesionnal tools we can't check this AFAIK. Don't worry about the motherboard. It was only a suggestion reported by a few users. Chances are your problem will be solved after receiving the new battery.
ok thought as much, battery charged up to 100%, rebooted and now at 60%.
Ill put back in the old battery for now and see how it behaves. thanks for you help

Low battery without anything consuming energy (OnePlus 3)

I hope this is the correct forum (went with this, cause the problem probably isn't related to my phone model, or is it?)
I bought an used OnePlus 3 from ebay and I have one big problem: The battery gets empty extremely fast. It even gets empty when I'm not using my phone. (lost ~15% in 1-2 hours while it was in my bag), when I go to the settings screen for Battery where it says which things used how much energy since the last full charge, the percentages add up to ~10-15%, even if my battery is at 10%.
Maybe the phone was just charged very often by the person who used to own it, would it be worth to buy a new battery? Or can this have other causes?

Honor 8 battery drain

Hello,
I am new here and need help with my Honor 8. The battery drain allot. I have read other post on xda-developers.com with the same issue. I don't know if the drain start after the update7.0. I just know that I know that my has been update to 7.0. If is some info:
Android 7.0
EMUI 5.0.1
I have tried to turn off WIFI+ and Location with no lock .
I don't know if my phone is factory unlocked and I will try to restart my phone but would like to know if I do that will take away the unlocked part?
Please share you battery graph and also see which app is consuming high battery. It may be many apps open in the background. I was facing the same and disabled Facebook on screen lock as it was consuming good amount of battery.
Check if you have enabled backup and sync for Photos as it consumes a lot of juice as well.

For the first time, mine did some crap like that this morning.
Word thing is the other day it stayed in 100% for 2 hours straight.
I mean I was web browsing on 4G, playing videos on YouTube etc. Doing everything I can to try and drain the battery.
My guess is we both need to factory reset.
In my case I recently updated to B391 but didn't factory reset.
Each update I did prior, I always factory reset the phone and had consistent & decent battery life

I mean I was web browsing on 4G, playing videos on YouTube etc. Doing everything I can to try and drain the battery.
My guess is we both need to factory reset.
In my case I recently updated to B391 but didn't factory reset.
Each update I did prior, I always factory reset the phone and had consistent & decent battery life

I always do a factory reset. It's crap, we users shouldn't have to, but it seems the best ways to squeeze the best performance of the device.
I bought the Honor 8 when it launched. It's almost been a year and a half and I had big battery issues.
I tried battery calibration, factory reset, etc... Nothing worked.
So I bought a new battery on Ebay (15€) and had it replaced. The phone is now good as new. At the end of the day, there's almost 50% of battery remaining.
I thing the component quality isn't that good and doesn't last more than 18/20 months.

I definitely agree. That's the Android way I guess

Thank you will swap my battery out soon. It's been working normally all weekend so we'll see if the battery Gremlins return again

I bought my Honor 8 around Octobor 2016 and same issue. Now, for common use, FB, surf with Chrome, IM with Messenger & WhatsApp, I've to charge 2-3 times per day.
My device is still in warranty (I think) then, I contacted Huawei/Honor support... but I think like you, battery is a poor quality and need to be replaced.

Could you please PM me the ebay link to the battery you got? Thanks
Is it easy to replace the battery on your own? I am really furious with the battery issues. Today my phone had 60% battery and it shut down suddenly. When I turned it on again the battery life was 0% and I was away from home without any other way to communicate with the universe ? . I don't know if I should by a new battery or just throw it away and get something else. It was a great value for money device (best camera ever!) but this thing with the battery is unacceptable especially because it is not easy to open it. I'd really appreciate it if you could send me a pm with the ebay link as well. Thanks in advance ??

Had my battery replaced under warranty a months ore so before the expiratin and with shipping taken care of (Huawei France). The phone was back quite quickly (took around one week) and now feels absolutely great. I am not a heavy storage user so I can manage with 32G for some time.
Even if it's out of warranty I'd say it's really worth replacing.
Hi everyone
I have my honor 8 two years now.
It always had 2days battery with normal use (videos included) for 1and half years.
Now it's switching off with 80% battery left.
When I plug it and turn it on it says 40/50% battery left. If I unplug it, it swithches off again.
It makes me crazy as I cannot rely on it, but the phone is fantastic!! I had other phones on the past, and the battery last for more than 5years!!
- I've reboot the phone already, cleaned the cache, checked all apps, but the situation is still the same.
Any suggestion?
- I'm reading that Google play might be the probem. Can I get rid of it?
Thanks for your help!
Cheers
Plinny
I resolved my battery drain problem by connecting all my wifi to 2.4Ghz instead of 5Ghz.
