Terrible stock battery life and won't accept non OEM batteries - AT&T Samsung Galaxy S II SGH-I777

Hey guys,
I've been lurking in the forums for the past year and lately I've noticed that my battery has been crapping out. I'm running CM 10.1-20130807-NIGHTLY-i777 (I update it once a month), i777UCLE5, with CWM 6.0.3.5.
With the stock battery I get just about 1.5 - 2 hours of active usage. If I listen to music on it for 45 minutes, the battery drains over 30%. This is with JuiceDefender on.
I invested in two Anker batteries which worked for about 2-5 months then started locking up my phone. When I rebooted, battery went from 98% to 13%. Happened to one of my two batteries in month 2, and the second battery crapped out in month 5. Then I got a so called "stock battery" from eBay -- had the same model # and everything but didn't have NFC on it. Crashes my phone and drains the battery instantly too.
I'm wondering -- is there any way I can make these after market batteries work with my phone? I'm guessing it has something to do with not having NFC. They probably have much better life than my stock battery but I just can't make use of them.
Any tips appreciated.

You need to search for the free xda version of Better Battery Stats so that you can take a more detailed look at what is causing your battery to drain.
You can find some great information by reading this thread.
You likely have something (or perhaps more than 1 thing) holding a wakelock that is not allowing the phone to get into a deep sleep and conserve battery power.

Thanks for the tip. I will try that out over the weekend.

You can use replacement batteries, but they will render NFC useless. Only OEM i777 batteries have the necessary equipment to make NFC work.
You may want to do a search in the Accessories forum here and see what people recommend.

Replacement Battery Question

Searched to see if this was already asked but didn't it.
Are the batteries in the Vibrant, Fascinate and Captivate identical. I need to get a spare battery today (if possible) and although the specs indicate it is the same exxact battery, I figure I'd better check with more knowledgable people.
Still trying to work out how to get a full day (8 hours) out of a charge (my only major complaint about the Vibrant - it is a great phone).
Thanks!

I know they are between the fascinate and the vibrant. My wife has a fascinate and we switch batteries all the time when mine is low.
Unfortunately I can't seem to find one at any retail stores. Tried a compnay owned AT&T and T-Mobile store (they had next to nothing as far as accessories) and Best Buy and Radio Shack.. Nada.. Guess I have to wait for the one I ordered from Amazon.. Really need one for Monday. Oh well.
Maybe I can conserve battery life by not using it :-(

This may be a bit extreme, but I've had much better battery life after switching to this custom ROM...
http://forum.xda-developers.com/showthread.php?t=782027
There are other tips as well, such as having your email check every 30 minutes instead of using "push" email, etc.
This is my first Android phone and I'm not comfortable (yet) with updating the ROM.
Without push e-mail, I may as well go back to my BlackBerry. I am already giving up Office Communicator and I can't give up push e-mail.
Unfortunately this reminds me of the early days of the iPhoney; battery life was dreadful there. Difference is, I like the Vibrant. And it has a replaceable battery.
Downloaded and installed JuiceDefender and purchased UltimateJuice. See how they work. Seems like a lot of work (between that and shutting off WiFi and BT and then remembering to turn them on). So it goes.
So far, battery life has been a disappointment.

I've always read that push was significantly BETTER for your battery than checking email at a fixed interval.
This is now depressing... Battery was 100% charged; 90 minutes later it is 70% charged. No phone calls. Very few e-mails (and I get a ton during the week). Two text messages. 10 minutes of web browsing...
So now I am uninstalling apps that I wanted like FaceBook and Twitter to see if I can find the major drain. And I won't be able to so I'll have to go back to my old phone. Very depressing. I checked with someone else in my group. Same thing.
How do people who need push e-mail and IM deal with this? I am 100% positive it will get better in the future, but I can't wait
Check ebay. I got two batteries and a battery charger for around fifteen bucks. Works great....also try calibrating your battery meter by letting the phone completely drain then completely charge it. Doing that a few times every now and then defin helps my battery meter

I ordered a spare battery but it won't be here by Monday. I won't be anywhere near a power outlet Monday and can't have this thing die at 11AM...
Extended battery
I bought an extended battery from mugenbattery.com. It's for the Galaxy S i9000, but since both that phone and the Vibrant are practically identical inside and out, it fit perfectly. After unplugging my phone for about 8 hours, after light use (bluetooth on for about 30 mins and a few email checks), my battery was down to about 92%. With the stock battery it was down to the upper 70's. Also all the gel cases and leather cases for the i9000 will fit the vibrant (i have one of each). Mind you, the phone with the extended battery will feel heavier and will be about twice as thick, but I don't care. I got juice now for pandora and angry birds all day baby

ICS ROMs and the battery charging issue, possible cause?

In the CleanROM ICS thread, Marine6680 posed an observation that I think bears looking into.
Please vote only if you are using an ICS ROM.
EDIT TO ADD***
Also please vote based on how your phone behaves while it is turned on. If you experience different behavior when the phone is off, please post that as a response.
END EDIT***
Marine6680 said:
I have both the stock and the extended battery. My stock battery has stopped charging fully, only to 92%, my extended charges normally. My fiance's battery will not charge fully either. It is stock as well.
So it could be that these new 3.8v batteries (which are tweaked chemistry versions that have a slightly higher voltage than standard 3.7v) are not supported by the new kernel's charging controls. (which seems odd that it wouldn't) That is, if that is even controlled by the kernel and not hard wired into the mainboard.
So it may be an issue with the batteries... or not. If it only happens with the stock batteries then it will be harder to say for sure.

I've posed the question in both the CleanROM and Ineffabilis ICS threads, but figured I'd post here to try to get all ICS ROM users to see it.
So far, all responses in those 2 threads have been that people with charging issues all had 3.8v batteries and that people with no charging issues (myself included) had 3.7v batteries.
Please respond here with your findings. Just pull out your battery and look on the back, top line of text.
I'm not sure what can be done about it, but at least it would answer a question that seems to be annoying a lot of people across ALL ICS ROMs.
Great idea for the poll, but still wrong section. Should be posted in General.

Sorry. Can a mod please move?
I have the 3.7 battery and have had no issues with charging at all.
I have a 3.8 for about another 3 hours. I'm stopping by Verizon and getting a 3.7. I dare them to try to tell me no.
I have a 3.7 with no charging issues.
Well, my battery lasts like 2 hours since I put ICS on there but I can't tell if thats the usual terrible Rezound battery life or something wrong with my rom.

If I charge too 100% while it's turned off (since I have the 3.8v battery), I get great battery life on ICS. Yesterday I got around 16 hours with 4g on all day under normal use. On stock GB and the two GB roms I tested out, I was getting between 14 and 15 hours on average with 4g turned off.
If I try to charge with it turned on and experience the 87% ceiling, I get horrible battery life. 10 hours max, and the battery seems to discharge very quickly when I'm actually using it.
on my De-Sensed ICS Rom it doesn't charge up to 100% pretty much stops at around 98%~.. I have pretty amazing Battery life Could go an entire day with out hitting 20%, but then again I don;t have alot of apps
I have a 3.8v battery, running ICS, no charging problems, no battery life issues.... no nothing.
The ONLY strange issue I have, and I've had it since day one on GB, is that when i unplug my phone from the charger it will say either 99 or 100% on my battery widget, however if you wait a bit and then look at the battery stats chart later in the day, it shows that it began discharging from 93-94% rather than 99-100%. I simply assumed the battery scaling in software was slightly off from what the battery itself is reporting, but since it doesn't seem to be a problem at all I have just ignored it. The battery easily lasts all day with plenty of juice to spare for me.

wow, 10 hours is bad battery life on a lte phone?
If you aren't in a LTE area, make sure to set the phone to CDMA only instead of CDMA/LTE since it will forever search for an LTE signal... Thought I'll share that little tib bit.
Oh and In my situation I'm always connected to Wifi, Home,School, Work so I go into *#*#4636#*#* and under Phone Info I switch to CDMA only (1x) instead of CDMA Auto (3G) since in my commute I'm not stream/downloading anything... So keeping the Phone at 2G all the time makes for an even better battery life
But To each their own
** Since the issue is more ICS centered, I (among others) would blame this on the Leaked (unstable) battery/power drivers... So only until the official release we can't blame ICS as a whole (for now)

Got 1 day 4 hours with 40 percent left on your rom everything left as is. My issues with the music player was the only reason I went back to GB. That issue was across all ICS roms.

Maybe "horrible" was an overstatement, but it's certainly worse than what I was getting on GB or when I'm actually able to charge fully. That's also with 4g disabled, which I should have mentioned.
I have 2 different rezound batteries and both are 3.7v and had zero charging issues with any of the ICS roms I've been running.

[Q] Battery issues.........

I've had my Flyer a few months now and in the last few days the battery seems to be draining very quickly. I charged it full again last night and this morning it was at 88%.
I've turned everything off so just the bare bones of the device are alive and i'm using Juice Defender, and still no joy. It's only started doing this in the last few days so i presume the battery is on the way out very quickly.
I've let it drain to 10% and charged it, and it's made no difference.
I'm not going to mess about with settings and more waiting to see what it does etc...., I really just want to get a new battery and be done with.
Where can i buy a new battery? I've had a look on fleabay and no joy.
Any suggestions where to get one, part no. etc...?
Many thanks in advance

happened with me also....10% battery drained overnight...
what app is using most of ur battery?
sometimes push service in some free market apps drains a lot of battery and it keeps running even when app is closed... check running processes... well i uninstalled that app with push service and all became normal
Thanks for that but i've had a look through and it would seem that there isn't anything happening over night that i'm not expecting or that is being very hard on the battery.
I'm pretty confident the battery is the culprit here. Sourcing a new battery however is proving to be a problem. Somebody somewhere must be selling them.
I've just been on to HTC in the UK, they have a service centre not very far away from me and they won't sell me a battery or even give me a part no. for the battery.
Come on, somebody must know where to get one.
I think i might have found somewhere in China...
Battery - BG41200
3.7v - 4000mAh
If the prices were cheap enough how many of you would be interested in buying a battery for your Flyer.
Perhaps do a group buy?
i thought flyers battery is not user replaceable?
It's very replaceable and easy to do.
Here......

I'm going to have to look at getting a new battery sooner or later. It's getting to the point hat the battery is always running low by the time I get home in the evening or even running out. With pretty much the same use it used to be good for a day and a half easily. Flyer was purchase may or june 2011 so it really needs to last another 16 months or so.
Well......I ask again. If anyone knows of where to buy an internal Flyer battery please post a linky.
I posted this thread earlier today
"I just wanted to know what people are getting out of their batteries. I unplug mine around 7:30 am when i leave for work. When I get to work i turn on my wifi (rooted thunderbolt) and leave that on all day. I have the setting to turn wifi off (flyer) when screen is off. When I get home around 5:30 i switch to my home network and by 8-10 my battery is pretty much gone. Is this normal battery life or are there any tricks I'm not aware of that will help with battery. My wife has an Ipad 1 and she seems to get days of use out of it before she needs to charge it.
Also, I don't watch movies or video at work... most of my use is surfing, twitter and email."
I'm trying to figure out if what is normal battery life and If mine came with a bad battery. If so Yes I would be interested in getting a new one.
The Ipad battery has much longer life and is a much bigger capacity battery. The new HTC Jetstream also has a much bigger capacity battery as well. I think HTC have learned lessons on how much battery power these flyers use, but unfortunately have used Flyer owners as guinea pigs, rather like the first Apple iPhone but that had terrible battery issues as well although they've gotten better over time.
When my Flyer was brand new the battery lasted for ages and i couldn't understand what people were on about the battery not lasting for very long. So up until a few weeks ago my battery was doing fine and then almost within a day or two the battery started to run down quickly and has been doing so ever since. I've since loaded/unloaded new ROMS and done all the usual procedures for deleting the battery stats etc..., and still no joy.
I think the problem is with the battery not being man enough for the job at 4000mAh, and the drain is such that the battery is being worked hard since September last year (in my case) to a point where it is now progressively failing. I'm not so sure either that it's all that good in terms of quality.
Most of that time it has been charging from one source or another. If my Flyer isn't in the car or in the house it's not often being used battery only unlike most other people probably use the battery only a lot, so i can't understand why the battery is failing when it's not even that old.
This is a big issue with the Flyer and for what the device cost i would have expected a lot better. I think the Flyer in itself is a fantastic piece of kit that i will no doubt keep for a very long time as i did my XDA IIi but i never had problems buying another battery for my IIi. HTC will not sell me a battery, they insist i send the device to them and they will swap it but will cost about £50-£60 for the pleasure. I flatly refuse to pay that!!
What is required is a bigger capacity battery (6000-8000mAh) in the same packaging as the current battery however, i think for now i would happily settle for another of the same battery if i could just get hold of one.
So far it's proving an impossible task!!
Just to add: Once you've made sure there aren't apps being opened at startup that don't need to be opened until you're ready to use them, also make sure wifi/bluetooth, mobile data is all off when not required, and all the usual tweakes to make sure animations are off, screen is on the lowest brightness etc..., then there is not a lot more you can do. I don't know how much use something like Juice Defender will be as that only makes sure your data connections are off at night and other times you specify. I've tried it and it didn't help at all so i don't know what else to suggest apart from turning the radio part of the phone off completely at night if it isn't on charge.
If i leave my phone off charge all night, having fully charged first, i wake up in the morning and it's down to around 86-88% battery.

Problem with battery life

Hi, I have a problem with my Ace. When I only use 2G and use my phone for calls/sms, my battery lasts for like 3 days. But if i have 100% full battery and I use the internet with (or without 3G), my battery lasts for like half an hour, drains from full to 0 and then phone turns off. If i turn on my phone again, it shows like 30% or more battery left, but if data connection is still on, I lose 1 percent in like every second.
This is not only with data connections. I drained my battery from 100% to 0 in like 1,5 hours with just looking some pictures and using the calculator. I would like to think my battery is dead, but it lasts like 3 days when used for calls/sms only.
I have tried recalibrating my battery many times, used different ROMs (stock and custom), still same.
Is there anything else I could do to check my battery status??
Anyway, I am looking for a new battery but not the original one. Im looking from eBay. I contacted the sellers and asked for the weights. Original battery weighs like 30g. I got replied that these two (2050mAh High Capacity Replacement Battery for Samsung Galaxy S5830 and aoonen 2PK NEW Li-Ion Battery for Samsung S5830 Galaxy ACE 1800mAh fast shipping) batteries weigh 50g and 60g. This makes them less likely to be the fake gold ones, or what do u guys think? Has anyone bought one of those batteries? Or can anyone recommend a battery with more capacity than the original one (1350mah)
I accidentally hit "thanks" button instead of reply
I'm 100% sure that something is wrong with your battery.
I've never heard about such long-life battery in Galaxy Ace.
3 days calls and texting ?
It's normal that battery drains faster when using mobile data, but not that fast.
If You can, ask a friend to borrow You battery from Galaxy Ace.
If everything will be okay then You'll know the naswer.
If other battery won"t last longer, then i suggest to check you phone for "short circuit".
Maybe something is wrong with your motherboard that is connected with 3G .. ?
okay thanks, can I use the battery from S5830i?

I believe so, they both use the same sized battery (1350 mAH, Li-ion Batteries)

Hi,
I just bought two gold extended life (2450mAh) batteries for my Ace! I was meaning to test them against the stock one but hadn't got around to it yet. Didn't use the stock battery much as I think it's original to the phone which I recently bought 2nd hand.
If anyone wants me to do this test (properly) let me know.
Thinking about this; perhaps a few Ace owners could flash a common ROM and perform a standard discharge test. This would give us some baseline.

My batter is two years old and it works good.
I use CM7 and no super widgets. Maybe it saves energy.
Try another ROM, remove or switch off everything You don't need.
Maybe it will help You. If not, it's time to buy another battery.
Don't ask which browser is the best, because we don't know what You need.
I need my browser to browse websites. I don't use favourites on mobile phone, so everyone is the best.

There's an app called "Battery Drain". Try charging your phone to 100%, turn on Battery Drain and select everything except Vibrate, and let us know how long it takes to fully discharge.
I have a stock battery, and it lasted ~3 hours.

Wow, just too many variables! For instance.. Any idea how many mA the vibrator uses when typing with haptic feedback? What about the extra battery used by the radio when your in a poor reception area, does my micro-sd use more power than yours? Etc.
Battery life comparisons will only be meaningful in conditions where the battery is the only changed variable. So i would charge two or more batteries; discharge one, then another, measuring the times. Both batteries would need to be new unless you just want to compare something tired and worn with just out the factory.
Not 100% but I think it's relevant how many amps you take at a time, in relation to total capacity.. The chemical tech. may be difference, but lead-acid cells give differing amounts of charge dependent on temperature, and rate of discharge. In most applications capacity (C), is measured over 20 hours (C/20). C/100 will see many more amps capacity, and C/10, fewer! Also consider a used battery could last a considerable time, if only the high drain occasion is minimal. Something simple like the vibrator could send an old battery 'over the edge' if the drain is too high.
What does all this mean to me? Unless you wanna spend hours discharging your phone battery finding out (not really), get a fresh battery online; they still don't cost much and are easy to find. Gold batteries have been available for some time so go with your gut on that one! Perhaps, like me, you think it's worth the risk.
If you really love your phone and think you'll still be holding on to it in a couple of years time - you'll be thankfull you bought a spare battery or two while they were still cheap
Peace!

Hello, problems of battery are the most important in the management of smartphones increasingly sophisticated. I know of no silver bullet, so it makes sense to always have an alternate (note that battery life depends on time, even without use)
I found a small application, very cool, which is PowerTutor, which gives us interesting information from the battery usage. However'm with JuiceDefender Ultimate (free version exists). The only application which effectively spare battery was Greenpower. [all in gplay]
I hope I helped
new battery
Hi, new battery from ebay :laugh:, now lasts a day under normal use and a day and a half with little use of the internet.
Not bad for the low price
Seems that lastmyth that is not worse than the others in the use of battery.

This is usually the fix. It's amazing how fast some batteries start failing. Old batteries and cold temperatures are usually the top cause of poor battery life, especially in secondhand phones.
Try Juice Defender :thumbup:

[Q] KitKat/4.4.x and battery issues (regardless of the ROM)

I have been trying out various 4.4.x ROMs (CM, Resurrection Remix, SlimROM) and had varying levels of success but the one issue that I have had consistently with all of them on my SGS2 is battery. 4.4.x seems to devour my battery no matter which ROM I am using (and the different ROMS are using different kernels usual). CM11 has far and away been the most stable so I have stayed with that but it too as failed to resolve my battery issue. I have never had much luck with battery life before but half a day is ridiculous. I thought about trying a different kernel but not sure that would help as #1 I would think the CM team would know better than I what would be the optimal kernel and #2 I have been trying different kernels anyway when I have been trying different ROMS as I believe the different ROMS have all had different kernels. Has anyone else had this issue? More importantly has anyone had any luck resolving this?
I suggest you to replace your battery. Beaware from cheap ones!!! I have I9100 too, i also try many methods to increase my battery life but i reach maximum 10 hours. Then i buy new batteries. It is not original galaxy s2 batteries but i think better than the original one.(1800mAh buy from ebay) Now i use RR kit kat rom with stock kernel my mobile data is always on and I go to bed at %35 percent of batteries.
1. If your battery is quite old, replace it.
2. Check whether you are having any wakelocks. Does it go to deep sleep?
3. When you say battery life as half a day, what is your actual usage? Screen on time, Wi-Fi, 3g, calls etc?
4. Betterbatterystats and greenify are your friends.

Thanks. My battery is about 2.5 years old, its an Anker battery, 1900mAh that I bought on amazon (I honestly don't know what constitutes "old" for batteries, is 2 1/2 years old?). As for ROMS I was actually running an older version of RR but had serious stability issues (related to sdcard, never was able to resolve it) and battery wasn't great (better than now though) when I upgraded to the newest RR I had some lingering stability issues and battery issues too so just settled on CM11 this time.

Sorry, but what in your all's opinion makes for an "old" battery? 2, 3 years? or are we talking 4+ is there a way I could test my battery to see if it going bad perhaps?

2. Check whether you are having any wakelocks. Does it go to deep sleep?
I am not totally clear on wakelocks and deep sleep, I have "Battery Stats" installed (guess its not the same as the betterbatteryapp but seems to give some similar info) but its not clear to me how to read it all. In this case it sayd the stat period is 3 hours 8 minutes and out of that it has been in deep sleep 1h 51m and running time 1h 17m and wifi time 1h 25m and my batter is down to 74%, I am assuming that is not normal? In terms of applications the hogs are defintely the two audio apps poweramp and dogcatcher (they are just at the top of the list, the numbers it gives don't really make sense to me)

3. When you say battery life as half a day, what is your actual usage? Screen on time, Wi-Fi, 3g, calls etc?
Well I have a 3 hour idea of my usage above, I don't use 3 g, I have wifi on about a third of the day perhaps, and actualy screen time probably just an hour or two, I do use it quite a bit for podcasts and music though. But I had tried it with my audio apps uninstalled for a few days and it still drained fairly quickly.

Will take a look, I kind of liked the battery stats option to compare to stats that others have uploaded, but I haven't checked out greenify.

If your battery is 2.5 yrs old, that's almost certainly the cause of your issues. Good advice to stick to original Samsung batteries; though there's nothing wrong with the 2000mAh genuine Samsung battery Vs the 1650mAh one - I used one of these for almost two years.

Doh, was hoping I wouldn't have to replace the battery. Actually... that said. Should a 2.5 year old mostly unused 1650mah samsung battery still be good? I think I still have the factory battery around somewhere now that I think about it. When I purchased the Anker battery I seemed to remember it was mainly for price and reputation reasons, not that the Samsung battery had such a bad reputation but the Anker had such a good reputation and a pretty good price.
I will give another battery a try if you say 2.5 years is old, but I do have to admit that the battery drain was not nearly as much of an issue with the older ROM I was using (RR 4.2.x) before, it wasn't stellar but not like this so it seems to me its more than just the batter thats giving me problems here.
Anyway, my phone is still golden other than the battery issues so if i can squeeze another year and a half out of it I'd be a happy camper. Any other thoughts would be welcome (and appreciated!)
Batteries discharge over time if they're stored/not used, ideally you should charge it up to/keep it at around 60-65% every few mths if you're going to store it for that long. If you've not touched it at all in that time, it might not be able to take/hold a charge anymore because that wasn't done.
Only way you're going to find out is if you charge it & use it.
Yeah, if you ended up getting 4 yrs out of a smartphone you'd be rather happy indeed.
If you really want to satisfy yourself as to whether it is indeed the age of the battery you're currently using causing your problems, do a clean install of stock & test that for a week. If it does the same thing with stock, you'll know for definite it is the battery. I'd be very surprised if it isn't though; they're not designed to last much longer than what you've had yours if you're charging/discharging constantly.

doh, yeah haven't touched it; and the life lessons continue (didn't know that about batteries). will try it out, if its gone its gone, lesson learned.

Yeah, I suppose I am pretty easy to please, I don't do games and don't really do video and don't feel that my phone is particularly slow (yet) so so far happy enough

Thats a good idea, given what you've said i don't doubt that a large part of my problem is the battery (like I said before, with the older rom it was better but not stellar) do you know where I can find a stock rom nowadays? (sorry on the ROMS page they all seem to be custom roms, or perhaps i missed something?)
Thanks!
Stock roms @ Samfirmware, get one for your carrier/country (not 4.0.4 though, anything else is fine), if there's only 4.0.4 for your carrier/country, any other stock rom will do really -I just tell people to stick to carrier/country in the first instance as these have modems bundled with them that should have been tested by the carrier to give most people on their network good connectivity most of the time.
Or, Wanam has a thread in one of the development sections (I forget which; do a search or have a rummage around) that has CWM flashable stock roms if you'd prefer to do it that way; haven't had a look at the thread for a while so not sure if links are still live, but Wanam is a very active dev & I'd be surprised if he doesn't still have them hosted somewhere.
Does it drain more at a locationw where you use a certain Wifi?
I'm asking cause wlan-rx drains are know Android phones in big open Wifis as the phones get bombarded with signals from other computers/phones and are not filtered and keeps the phone awake.
Easiest way to find out is using Betterbatterystats.
