We always neglect the way we charge our mobiles, it’s very important to equally take care of your phone’s battery along with your phone. So, when it comes to the charging then you will have to ensure that you never overcharge your phone which means that never put your phone for charging over night as this may hamper the battery’s life very badly due to which you may even end up spoiling battery sooner than expected. It hardly takes 3 hours for phone to fully charge, so never charge your phone more than this time.
Also, many of the users tend to charge their phones regularly, like even if battery goes below 50-40% people tend to haste and put the phone up for charging. So unless and until you are going away from the charging point, it’s not a wise decision to charge it way ahead than the battery zeroing point. Make use of the AC chargers rather than using the USB points for charging the phone as basically the USB charging does the trickle charging which is not good for often charging the phone.
All batteries has the Golden color notch pins and with frequent pull outs these notches become loosely fit and are rubbed with the pins which leads to the wear and tear of the contacts and hence it decreases the life of the battery and the effective charging of the device is not passed on to the phone as the contacts in the form of pins gets loosen up. And also last but not the least never make use of the batteries which are not as per the prescribed specification chart which comes along with the phone and always use original batteries which can be purchased from Samsung.
Never put additional sim cards or anything like that in the compartment of the battery as this may cause some serious issue with the battery and may even explode at an extreme situation as every battery generates heat and it requires space to dissipate that heat and if its interrupted then it can be dangerous for batteries.
Unless and until you are not using the actual 3G Service, it’s better to choose the GSM Mode network rather than selecting Dual mode or the WCDMA Mode which drains the battery faster than the GSM mode.
Make sure that you set the brightness of the device to automatic and not to the fullest which is set by default, since it’s a touch screen phone back light should be not more than 15 seconds as that’s more than enough which can be done by going to HOME > MENU > Settings > Display > Brightness and Screen timeout
Make sure that You Tube, music listening, programs which runs in the background including the Sync option along with Bluetooth should be turned off whenever necessary as these too constitutes fair amount of battery drain.
GPS as well as the Camera eats up a lot of battery, so always remember to switch these both off when not in use or necessary and specially when battery is low then it’s advised to not to use these features which can be quickly done by setting the widget shortcut on the home screen itself, touch and hold on the Home Screen in the blank area and not on any app icon and select Widget>Power Control. Add this Widget to your home screen to choose the express settings

OP,
WTF - you can't overcharge your battery. The ROM/kernel doesn't allow it. The closer the battery gets to 100% the voltage is decreased further and further. At 100% there is just a small trickle that roughly breaks even with the demand of the phone. Telling people they shouldn't leave their phone plugged in for more than 3 hours is ridiculous. There was just a thread on here a couple of weeks ago where an AT&T employee told someone the same thing, and everyone was making fun of how stupid that advice was.
^+1 !!!!!!!!!!!!!!!!
Sorry, OP. You are passing off bad information.
Thread closed.
I've gone to using my spare xperia x10 mini pro now cause I've found while i'm out an about with my sidekick it will randomly get really hot an I don't mean like kinda hot i mean like feels like someone poured a cup of hot coffee onto thigh! The device hasn't been abused or dropped an its always had a tendency of getting warm at random it seams on all firmware versions. The only thing I can think of is possibly a issue with the phone connecting an unconnected often with the Bluetooth in my kia soul.
Now before you ask why I'm bringing this up now I had a none android samsung memoir befor this phone an it would get warm while GPS was enabled. Though in the sidekicks case it does it no matter what things are enabled or disabled x.x
So anyone else notice thier sidekick getting warm? with mine it seams like its something in the actual phone getting hot that in turn heats the battery up cause its around the DEL key on the keyboard.
are you running a 1.2 ghz kernel?
are their any wifi connections/bluetooth connections or any data transfer in the background that could cause your phone to clock itself @1ghz or above?
do you have any apps that run in the background (beyond the stock rom) while you are not using your phone?
your cpu could just be getting hot from background app usage while running @ the max cpu clock speed or overclock speed if you're on a overclock kernel.
The phone has never been overclocked an its done it totaly box stock with no wifi,gps,bluetooth activated an no data being used an has done this aswell with any connections enabled or doing transfers over blue tooth though since day one i do get a FC buzz when it first starts up but doens't say whats FC'd also notice when its getting hot that the battery amount is getting discharged by 10/20%
Hopefully it never got overcharged, or undercharged...
Have you ever turned it on after it turned off from 0% batt (or done this multiple times), I know that Lithium Ion batts have issues (I think it is 15% on the battery, but as 0% to the phone) if they go below 15% (0% in the meter) they will loose the ability to work correctly from then on out...
Calibration ever done at "NOT 100%", so it might think that 100% is 90% (or more) and try to keep charging?
Do you not charge it every night? (I have always charged all LiIon batts every night [mostly] and I have yet to run into issues with ANY batt.)
best to charge the battery with the cover off takes heat away from it
the odd part is that the battery never is warm while charging stays at normal operating temp for a happy battery. Now what I'm thinking is the battery is actually getting warm from something in the phone itself an transfering the heat towards the battery. An this phone has gotten warm like this even when it was less then a month old on box stock none rooted firmware of all types x.x
I’m going to try to consolidate a lot of battery information in this thread and prioritize it. This is a WIP.
1) Check your charger first!!!
2) Fix wakelocks
3) Remove bloatware
4) Replace your battery
5) Try a new ROM
The Charger Problem
Using certain chargers causes a wakelock on your phone that prevents it from going into deep sleep. This results in roughly 10% battery attrition, regardless of activity or screen on time. Before you try anything else, you should test each of your chargers and make sure they aren’t causing a wakelock.
Do you have this problem?
Install CPU Spy from the Play Store. Open the app to see how much time your phone spends in each CPU state. If Deep Sleep is a very small percentage, or Deep Sleep doesn’t even appear, you have a problem with your charger. Follow one of the methods below to test each of your chargers.
Charger Test App
I've created an app with the sole function of reporting your charge type and current. See the thread below to download and install the app.
UPDATE: This app is now available on the Play Store for easier installation: https://play.google.com/store/apps/details?id=com.jellisapps.srchargertest
http://forum.xda-developers.com/showthread.php?p=29451951#post29451951
Testing with only CPU Spy:
1) Plug your phone into the charger and turn the screen off. Leave it charging for about 30 seconds. (Don't do this with a fully charged phone, as I don't know how that affects the testing)
2) With the screen still off, unplug the phone from the charger.
3) Open CPU Spy, hit the menu button, and "Reset Timers". Turn the screen off.
4) Let the phone sit idle for a few minutes with the screen off.
5) Turn the phone back on and refresh the timers in CPU Spy (menu button again).
If Deep Sleep doesn’t appear in the list of CPU states, your phone is experiencing a wakelock brought on by the charger. It’s probably spent the majority of time at 192mhz or 384mhz.
To further confirm this, leave your phone unplugged, restart it, leave the screen off for a few minutes, and then check CPU spy again. You should now see it going into Deep Sleep.
It’s rumored that some USB cables can also cause this problem, even if used with a good charger. I have not experienced this with the cables I’ve used.
Testing with Terminal Emulator:
This method will not show the wakelock, but it will show you what charging mode the phone is in. Because I’ve identified the problematic charging mode that creates the wakelock, this method can be used to test your chargers fairly quickly. (Thanks to pj_rage)
If you have Tasker, you can download and import my Tasker profile that will check the charger when it’s connected and toast you with the charger type. It will also pop a notification if the charger will create a wakelock. Profile: https://www.dropbox.com/s/jewrvalkc7agtoz/Charger_Type.prf.xml (hat tip to Note-owner G8351427 for the Tasker idea)
1) Plug your phone into the charger you want to test.
2) Use your favorite terminal emulator (ROM Toolbox has one) to run:
cat /sys/class/power_supply/battery/charging_source
3) Look for your results:
0= No charger connected.
1= USB Normal Charge. There is 5VDC on pins 1&4 and data current is detected on 2&3
2= AC Fast Charge. AC Fast Charge. There is 5VDC on pins 1&4, and pins 2&3 are BRIDGED.
6= AC Regular Charge. This is the charge state that creates the wakelock. There is 5VDC on pins 1&4, and pins 2&3 are OPEN/DISCONNECTED.
Thanks to SR-owner nighthawkmckenzie for additional information on charging states.
Known Workarounds:
If you can't use a proper charger, there are two known workarounds.
1) Restart your phone after charging. This is what I did for a while, until I found one of my chargers that works with the phone.
2) Plug your phone into a "Type 2" charger. If your phone is plugged into a Type 6 charger, it creates the wakelock upon disconnection. But if you plug in a Type 2, even briefly, it clears the wakelock. For example, I would charge my phone overnight on a Type 6 charger (leaving a wakelock), and then just plug it into my car charger (Type 2) for a few seconds on the way to work to eliminate the wakelock.
3) Mod your charger to bridge pins 2&3. Instructions can be found here.
4) Buy one of these adapters. I have not tested this, but Note users say that it increases the charger current for chargers without pins 2&3 bridged. Theoretically, that means it should be recognized as 2 instead of 6. Someone let me know if you try it and verify effectiveness.
5) Turn on your screen before unplugging the phone. Some users report that this works. I've been unable to get it to work for me. Try it with your charger using my testing steps above if you'd like. (This workaround is courtesy of Note-owner ultravorx)
Why This Happens:
Thanks to pj_rage's research and nighthawkmckenzie's help putting the pieces together. As stated above, the Skyrocket and the Note detect if pins 2&3 are bridged or not. It seems that, for chargers to be Apple certified, they must not bridge pins 2&3. These chargers don't cause a big problem for most phones, but they do for ours. It lowers the mA current and causes a wakelock that persists after the charger is unplugged. The wakelock I usually notice is sdio_al, which seems like it's related to I/O on the SD card. Perhaps detecting a cable connected without pins 2&3 bridged, the phone is preparing for data, then fails to terminate the wakelock.
Here is a really good thread by pj_rage with information on chargers and the Note
My phone takes FOREVER to charge!
Not all chargers are created equal. Some of them enable quick charging, while some of them do not. Plug your charger in, open your Terminal Emulator, and run this command:
cat /sys/class/power_supply/battery/batt_current_adc
Divide the result by 10 to determine the mA rate of your charger. If the result (after dividing) is close to 1000, quick charging is enabled. If the result is close to 5000, quick charging does not work with your charger.
Wakelocks That Destroy Your Battery Life
If you're not familiar with wakelocks, they're basically processes that run on your phone that prevent it from going into deep sleep. Deep sleep is the mode your phone should go into when you're not using it so that it can conserve battery. Some wakelocks are intentional, while others can be the result of rogue apps or system processes.
For an excellent and thorough guide to Wakelocks and the Skyrocket, check out this thread started by T.J. Bender.
To effectively find your wakelocks, you'll need BetterBatteryStats. It's free to us XDA users. You can get it in this thread. Read that OP for more information about wakelocks.
AudioOut_1 - Hat tip to T.J. Bender's post in this thread for information on AudioOut_1.
Settings -> Sound
Turn keytone, touch sounds, screen lock sound and vibrate on screen tap off.
sdio_al - This is the wakelock created by your charger, detailed above in this OP.
Clean Out the Bloat
Some of the bloatware and unnecessary apps on our phones can drain battery. Here is a good thread by Earthdog that is stickied in the Themes and Apps forum that tells you what apps are safe to freeze or uninstall. I really recommend you freeze the apps in Titanium Backup and run for a few days before you uninstall. This way you won’t accidentally uninstall something your phone needs to remain stable.
We’re Gonna Need a Bigger Battery
Many Skyrocket owners (myself included) have discovered that the Verizon Galaxy Nexus extended battery works pretty well in the Skyrocket. The Skyrocket’s battery is 1850mAh, while the Nexus extended battery is 2100mAh.
Here’s the thread discussing the battery.
It costs less than $25 at a Verizon store and will add over 10% to your battery capacity. The battery is also made by Samsung and has built in NFC, just like our stock battery.
Some people report filing down the battery so that it will fit in their Skyrocket. I followed the advice of user stevenlong and took the sticker off of the outside of my extended battery. Picture of his battery is here. After this modification, it fits almost perfect. The slight bulge is not noticeable unless you’re looking for it (that’s what she said).
The Stock ROM Sucks
If you’re still unrooted and on stock Gingerbread, I feel sorry for you. What the heck are you doing on this forum if you’re scared to flash a new ROM?
This guide would be way too long if I tried to explain the battery improvements you might see by stepping up to the Stock ICS leak. You’ll probably see even more improvement if you flash one of the many custom ROMs in the Development section.
If you’re dedicated to getting the most out of your phone, spend a weekend reading the ever-loving sh*t out of the stickies in the Development forum. Only after you have read those threads and feel like you have a good understanding, backup your phone and flash a new ROM on it. As long as you’ve backed up properly, you can flash between several ROMs and choose the one that works best for you.
If you have any questions about the ROM you’re trying to flash, ask in the Q&A forum. Don’t start out by asking in the ROM’s threads, unless you’re POSITIVE that the question has not already been answered in the thread or the stickies. You did search first, right?
I can only speak to my own experience, but SKY ICS by seanzscreams has been AMAZING for battery life. I’ve really wanted to try some of the other ROMs, because they look good as well, but SKY ICS has been so good that it’s hard to think of using anything else. Try them all and see which one you like the best. Don't forget to donate a few bucks through the donate button for your favorite ROM's developer!

That guide seems to cover Wifi and BT drain issues with the GS2. I'm not sure how similar our Wifi and BT is to theirs. Our phone hardware is closer to the T-Mobile GS2 hardware than the AT&T.
In my experience, our phone and the AT&T Note have the charger issue. I just tested my wife's AT&T GS2 and it does not have the problem. My problem charger that gives me a wakelock (and is reported as type 6) does not give her a wakelock and is reported as charger type 2.
I'm editing the OP as I discover more and more information and perform various tests today.
I think I've discovered that the wakelock is ALWAYS caused by using an iPhone certified charger (or one that the Skyrocket thinks is iPhone certified). To be certified for iPhone, the charger must include a special circuit that identifies it as such.
I also created a Tasker profile to easily test your charger. The profile reports your charger type when you plug it in and creates a notification if your charger will cause a wakelock.
I would really appreciate if some people can test these theories out. In my experience, chargers that are reported as type 6 ALWAYS create the wakelock. Any reported as 1 or 2 do not.
ALSO: I've always used Stock and Sky ICS. Can someone on an AOSP-based ROM check a known iPhone charger to see if it reports type 2 or 6? This can help us determine if this problem only exists in the Samsung-based ROMs.
Very good info, I checked a couple of my chargers and they were working properly. Thanx
Edit..
I just checked my car charger, bought it at [email protected] when I got my skyrocket. On the attached charging cable it reads 6 in term. Emulator, and if I plug a cable into the USB connection it reads 2.

I am running CM9 nightly 7/7 with Instigatorx kernel, and I just tested the following chargers with the same cable:
Stock Samsung Skyrocket
Stock Motorola RAZR
Stock Palm Pre
Stock 1st gen iPad
All but the iPad report as 2, the iPad reports as 6.
Also, I tried your Tasker profile but it says it can't find /mnt/emmc/chargetype.txt

Thanks for testing.
I also flashed aokp earlier and charger behavior is the same. I wonder if this means it's a hardware problem, not software.
Chargetype.txt should be created in /mnt/sdcard/. I'll have to look as to why it works different for you. You can try changing the path for the read task in the meantime.
No worries, I just manually cat'ted the file. So far I haven't seen the charger wake lock recently on my setup, but I'm still investigating. I am seeing a lot of 'deleted_wake_locks', which may be related to my tasker profile that turns off Wifi and BT during the day.

You're not seeing the wakelock after using your iPad charger? In my experience, plugging in to a type 6 charger immediately eliminates the wakelock, even without restarting the phone. The wakelock seems tied to the last charger you used before unplugging.
Thank you very much for this useful post. I sometimes charge my phone using my usb port on my MacBook at home (it's a work computer--I hate Macs), and I wonder if using that port is causing a wakelock issue for me. I charge it on that and then leave my phone off the charger at night, and when I wake up my battery is usually depleted by 15% minimum by morning (running CM9 nightlies currently).
I'll test it out tonight and report back (if I remember to...which I should...lol).

A 15% drain over an 8 hour period of no use seems normal to me if you have accounts syncing. If you had the wakelock, it would be more like 50-80% drain over that same time.
Your MacBook should report charger type 1 (USB charging), but please let me know if it causes the wakelock (using the CPU Spy method).
I've been using an app called Juice Defender, it's a pretty nice app that will turn off your radios while your phone is in standby mode. I can set my phone on my night stand when I go to sleep and leave it for 8 hours and get anywhere between a 7-11% percent drain. There is three levels of the app (free, pro, and ultimate)
sorry I can't link it cause of the 10 post rule
Just my two cents...

A lot of people use Juice Defender, but the app is very polarizing. Some people claim it's made their battery last forever, while others say it's the same or worse with JD. I used it briefly on my Nexus One and didn't notice a difference. I didn't include it because of the controversy surrounding its effectiveness.
I'll look around and see if anyone has a really good thread explaining its worth and link it in my OP.
My issues with the SR battery have been around the syncing that happens in the background. I finally got my work email down to syncing once and hour and gmail to once every 2 hours. Obviously this varies per person but I think how often the phone sync's is Androids worst enemy. With Juice Defender at least you have somewhat "universal" control over the radio's and when they connect when YOU want them to.
Whether or not you get better battery is in fact subjective to the user.

As far as I understand push email, you shouldn't see much, if any, battery improvement by delaying gmail because it's pushed, not polled. Increasing polling intervals on Exchange email will help, though.
And you're right, the biggest factor in battery life is how people use their phones. The thing I hope to accomplish with this thread is to eliminate the problems that ruin battery life regardless of how someone uses their Skyrocket.
My charger was recognizing as 2 (AC fast charge) but I switched to OEM just to see and it does indeed seem to be idling much better and charging faster. Go figure.
I do suspect this is partly a software issue, but if using the OEM charger works, it works. Good thread.
Thanks for the good info! I try to monitor my usage as much as possible and once I root my phone it will be a lot more flexible, but some new stuff in here I'm gonna try out as well.
Thank you so much for putting this together. I wrote a couple of scripts in ROM Manager to test all of my chargers, and the two Griffin dual-USB car lighter chargers I have both return a 6... After reading this thread, it's not surprising because Griffin is in bed with Apple, and pins 2 and 3 must be open to receive Apple certification. My bad, but I like the Griffin products, and think they are robust and designed well. I've used them with my iPods all along...
I unplugged my Skyrocket the other day when I went to play golf, and used my Golf Logix GPS app. I had a full charge when I started, but I noticed the charge dropping rapidly as I played, even though I kept turning the screen of constantly. By the end of a full round (18 holes), my phone was down to 14%! I figured out was the golf app and uninstalled it, but afterwards, when I checked in CPU Spy, I found that my phone never slept the whole time, even with the screen off...
Turns out, out must be the charger in my car. It's currently cracked open, awaiting my soldering iron and my 1 year old girl's next nap
Thanks again!

Is Juice Defender worth it? With AOKP and many other custom ROMs you get toggles for data/wifi/brightness; shouldn't manually regulating their on/off state be just as efficient (if not more) than automated control? Or am I missing some features that Juice Defender carries

It's a simplicity thing for me. Yes, I could flash a custom ROM and configure everything manually to max my battery savings. Or, I could root the phone, freeze bloatware, and set JD up so that it handles all that for me. I'd probably have somewhat longer battery life doing it the first way (or significantly longer, depending on the ROM), but my battery life with JD is fine for my purposes, so why mess with flashing a custom ROM, the ever-present brick possibility and resetting the flash counter later when I can just root it and forget it?
Hello all, so the original battery on my Google pixel, almost 3 years old, went to complete hell. It turns off in about a minute once unplugged, despite 100% battery life. So I went and replaced it with two Amazon bought batteries. The first one (definitely not OEM) had the same issue but my pixel would at least last about 10 minutes of regular use, unplugged, before shutting down. So I thought it might be the battery but the second one has the exact same issue. The second one at least looked like OEM with the exterior but since it came from Amazon, it's not 100% certain.
The problem is that the phone charges very fast, like 100% in less than 15 minutes and then discharges 10-20% in just a few minutes. If I last below 70% that would be out of the ordinary.
Is it possible that it's not a battery issue but maybe a different issue? A friendly person on another forum suggested that my core or graphics IC is overheating, attempting to throttle down; and then just shutting down when it looses the battle. Which makes absolute sense since the phone mostly shuts down when I'm playing games on my phone and usually turns off just under 80%.
I also found out that a recent google play store version was found to be the culprit for the extensive battery loss for other folks. Could this also be reason?
Are there any tests I could do to further determine the actual cause?
Thank you.
Two ideas:
- Deactivate Play Store app in Settings -> Apps & Notifications -> All -> Play Store -> Deactivate
- To rule out a damaged third party app as a cause for the battery drain (which actually is quite unlikely in your case), you can reboot into safe mode. For that, long-press the power button and then long-press 'shut down', confirm with OK. At the reboot, all non-system apps are freezed. Then you can check if the battery behaves differently.
Did you try charging your phone for about two hours longer, even if it says it is already at 100%? Maybe just the battery percentage measurement system is somehow damaged.
But you already tried that I guess. So maybe somebody else got another tip for you.
do you try flashing stock image? maybe the battery cache is in trouble
Similar to OP, my Pixel XL had started to have some odd issues beginning almost a year ago. It got REALLY bad in just the last six weeks or so when it would shut down at relatively respectable battery percentages (something like 23% - 57%, randomly).

Thanks for these ideas, BenjyTec.
When I deactivated ("Disabled" in my settings), there was no change in behavior. In fact, I had forgot I did that until giving things about a week and had forgotten when the phone behaved the same way, LOL (I just now re-enabled it).
I also tried the Safe Mode (which I had not previously known about - thanks!), and the phone still died out pretty quickly from a "full" charge.

I had also done this several times. The really odd thing is many times I will have it on the charger all night or for several hours, and when I take it off it is only at a very low percentage - from 1% to 16%. !!! Of course more often than not it does get to a higher percentage.

Thanks, gonzakennyn - I have not done a "stock" image, but have factory reset the phone, with no joy. This was actually one of the things I did months ago even before it got really bad, because I wondered if maybe the battery cache or something at the kernel level had deeper issues.
Hopefully the OP might have had better luck or found something...
All these complaints sound like power supply issues.
Use the phone while it's in the charger, and there's no overheating/throttling/shutdown, right?

I had also done this several times. The really odd thing is many times I will have it on the charger all night or for several hours, and when I take it off it is only at a very low percentage - from 1% to 16%. !!! Of course more often than not it does get to a higher percentage.
Thanks, gonzakennyn - I have not done a "stock" image, but have factory reset the phone, with no joy. This was actually one of the things I did months ago even before it got really bad, because I wondered if maybe the battery cache or something at the kernel level had deeper issues.
Hopefully the OP might have had better luck or found something...

Unfortunately, I did not find a solution. After replacing the battery twice I pretty much resigned to my fate. I'm going to hold out until Pixel 4 comes out.
Once fully charged, I could use my phone for browsing or watching videos for about an hour before I get to around 30-40%. Then I could leave it unplugged all night and wake up to my battery at 1%. It actually stays that way for a bit.
However, if I use my phone to play any games, I could only use it unplugged for about 10 minutes. My phone will power down without fail at 80% or below only when I play games. Weird thing is, whenever I power it back up, my phone will be 1% but despite that it could last quite a while.
As post-mortem mentioned, I could use my phone while charging without issues so maybe it is a power supply issue, in which case, I have no idea what I could do.
When it's not plugged in to a charger, the only power supply is the battery. Hence, I feel that even your "new" battery is not new.
So a little update all. I updated my phone to the latest Android 10 patch and the battery life has gotten significantly better. It's still not enough to last all day but it can last probably 6-8 hours with minimal use. If I use it constantly, it might last two hours.
I am no longer tethered to my charger when playing games, which is really good news and all the prior issues with the phone shutting down ~80% is gone.
Perhaps the previous Android patches contained faulty code?
I would do fresh install and see if problem resolves. Fresh install fixes all sorts of software issues.
So my battery woes aren't as bad as yours but I did get to the point where I had the battery replaced. I went to uBreakiFix and I have no idea what battery they put in but the bottom line is a brand new battery didn't help much. I got a little better battery life but not as much as I had hoped. I'm assuming that it's either due to the apps I have installed and my usage or the phone is getting old and something is drawing a little more power than it used to. I have not gone to the trouble of factory resetting to see if that would help yet.

Factory resets didn't help my old issue. Updating to the latest Android os helped immensely. As stated above I no longer have the initial issues. I estimate I now have about 70-80% capacity, which is not bad at all considering I bought my battery through Amazon for around $20.
I thought if you got your battery replaced at ubreakifix, then they are obligated to fix your issue or refund you your money.
