Defective battery?

Battery consumption is going trough the roof lately..
Can someone tell me if it is normal to go from 56% to 28% in an hour of surfing and listening to music? (see screenshots) Screen brightness is 10% and just surfing, no downloading from the market etcetera..
I think it's unacceptable.. Took my phone from the charger 7:30 this morning, i charged it at work from 50 to 60% in the afternoon.
Current charge is 17%.
I already changed my ROM (clear cache, dalvik, storage) and radio but it doesn't seem to help at all...
I ordered a replacement battery for only 10 euro at ebay so i hope it will solve the issue..
Also, is there a known fix for the 90% charge on wakeup? It's rather annoying.

Yep thats 3G for you.. I've just been doing the same fir about 10 and already a 15% drop.. at least yiu can change the battery unlike the iPhone..

That's ridiculous.. Are you telling me it's normal to drop a percent per minute when actually using the device? (happened to me the other day)

Yeah I hear you. This phone has absolutely pathetic battery life. Even worse than an iPhone! Even using SetCPU to underclock it has little effect.
Just 10 minutes after unplugging it from the charger its at 94%. Another 10 minutes later its at 89.
Disturbing.

If you are sure you don't have an app running in the background, or a badly coded app draining your battery, I'd try THIS. I get around 48 hours of medium use on a full charge.
Calibrating the battery made a massive difference to me.

I forgot to mention that in fact i did calibrate my battery. Twice. Already 6% down in 10 minutes as we speak.

Im not trying to be rude but im assuming you have checked all your settings & applications for wakelock bugs and syncing related stuff?
You should roughly have ~1% per hour consumption when idling(screen off).
Try typing *#*#INFO#*#* and see battery history for any abnormalities, like way higher "running" % than "screen on" %. They should be pretty much equal.

Yes i checked all those things numerous times also no abnormalities in applications sucking up all the juice.
I think we can conclude the battery(consumption) just sucks monkey balls.

When your battery is fully charged go to phone and type the following. *#*#4636#*#* then tap battery information. It should say battery health good, and then Battery voltage. What doe that read?
I'd also try calibrating the battery again, following the instructions to the letter. If all else fails I'd try a factory reset and run it at stock for a while to test and ensure you don't have a rogue app.
One thing I'd say about your cheap replacement battery. They are never going to be nearly as good as an original, as they are mostly poorly made and deliberately wrongly labelled to make them look like they are high powered, and at worst can be dangerous. Just be careful with that one.
I really can't understand why you would have such poor battery life. I'm happilly getting at least 48 hours with mine. I have wifi and data enabled all the time, use it a lot for twitter, make a few calls, and send texts.
Anyway, good luck and let me know how you get on.

Cheers for your reply,
I checked using *#*#4636#*#* and nothing out of the ordinary to be honest.
When fully charged it's around 4100mV so that should be ok as well.
About the cheap battery, it's from E-cell in the UK and my previous purchases were of good quality. So will see if it's crap or not

Having the same issue as you. Bought my phone 5 days back and I calibrated the battery too. No sneaky app trying to drain the battery.
Will wait for couple of days and then as suggested will reset the phone to factory settings and then check.

Check spare parts app. Look at partial wake usage.
Sent from that one Guy.

go to about phone, then battery. see if awake and on time is the same. if they are, bad. then go into battery usage, and see what the graph looks like.
then open up spare parts, go to battery history, hit the top box, and select partial wake usage. see if anything is not normal aka filling more than a few pixels at all. then check all the other top box options to see if anything isnt normal. then we can diagnose.
what rom/kernel?

Thanks for expanding on my vague reply. You deserve a cookie.

That dosen't sound horriable, how long do you want the phone to last? I tried a sbc kernel with my extended battery and started getting crazy batterylife like 85 % after like 15 hour off charger with data off, and little use, mostly txting other then the risk of exploding battery I am considering going back to the sbc kernel. I am trying one of the new hdmi netarchy kernels
I learned turning data off can make ur phone last forever, if I plan on going out I will usually kill data, and turn it on when needed.

What exactly causes this? Every once in a while my battery, which is normally fantastic, seems to spring a leak! I installed spare parts and check it from time to time to make sure nothing is going bananas on me. Today I noticed that within about 5 hours of unplugging my phone, two quick calls, and a few texts, my battery was down to 65% (and still falling). I checked spare parts and under "other usage", it shows "running" 100% since last boot. Partial wake usage shows android system nearly full. This doesn't look right, and it certainly isn't acting like it does any other day.
I'm currently using ultimate juice. I have system panel and watchdog but I honestly haven't even reinstalled them since I rooted a few months ago. (Battery has been that good with MIUI...) Maybe I should??
Spare parts is new to me. Just downloaded it the other day, then this battery thing happened, and while scanning the forum just for ****s and giggles as I do every evening, I saw this post. Could somebody make light of this for me? Thanks...

same problem here i was unplugged for five mins and i lost 4 percent battery! hate it!

srry but most battery problems which have no solution are from a bad match of kernel, rom, and phone. just keep flashing stuff until your phone likes something. thats why some evos (even never rooted) get 1300 quadrants and 30 hrs battery and others get 800 quadrants and 5 hrs battery.
edit: if there is a problem though, then it is fixable. i just dont know much more on how to find it besides that....

Yeah some days are better than others

[Q] My Stand-By time is about 10 Hours

If I were to leave my phone on without using it, it would die in about 10 hours. Is this normal? It's been like this since stock. I don't think this is normal since my G2 had way better stand-by time.
Please, don't say it has something to do with your settings and stuff, because I had the same things turned on with the same apps on my G2 with way better Stand-by time. GPS and Auto-backup.

Im running bone stock. I recharged after 38 hrs. And still had a 30% chg left
These were 14 hrs after complete chg.

See? This is what I'm not getting. Even since stock my Standby time was horrible. So I rooted to get better battery life. Nothing is changing. I even did a battery calibration to see if the phone was just reading the battery wrong.
I have another question. After the phone is finished charging at 100%, as soon as I take it off the charger, it goes down to 99%. Is that normal? I thought the phone was supposed to stay charged at 100% for a little while.

I just unplugged mine from complete charge and as soon as I unplugged it went to 99. So, yes????

That is normal to drop to 99% immediately. I always charge to full before I go to sleep at night and for some reason if I leave wifi on, the drain is really low when not in use...

Ok. I have no idea what is going on, but my phone just randomly rebooted, froze and then reset my home screen replacement launcher (as if I hit set to default), and now when I went to check on the battery usage and this is what I get:
Android OS is now at about 2% along with other things.
Display is at about 50%.
This is new. Android OS used to ALWAYS be higher then display. That didn't make since.
Now things are different. It seems the display is using the most energy. That is normal. I expect that.
I don't know, but it seems that everything is back to normal. I am using the phone, so I'm expecting this battery drain, but I'll check to see how much battery is drained on stand-by when I go to work later on today.

If you want your phone to last you throughout the day, make sure that "Use Wireless Networks" in Settings -> Location is unchecked. That is the biggest battery guzzler this phone has next to 4G and Brightness. My battery loses 2% all night til I wake up (Thats 8 Hours!!)

I figured it was a Samsung thing. I leave GPS off if that's what you mean, but location services stay on. That's just a me thing.
///////////////////////////
Today after work, I lost 30% energy on standby. That's alright with me. It was about 6 hours of straight standby time. It seems to have gotten better. At times I'd lose at least half of my battery after at least 5 hours.
I don't know how the phone seemed to fix itself, but doing things doesn't just DRAIN the battery anymore. I was playing on the phone fixing my home screen launcher and my battery wasn't dying right in my face. I lost like 2% after having the screen on for about 20 minutes fixing up my settings compared to seeing 5+% in like 10 minutes.
I am satisfied.

Lol, your battery didn't fix itself, that sounds like somethings wrong with the battery cycle. Maybe you need to recalibrate it.
You see, sometimes if you overcharge a phone, especially when using a charger that isn't made for that specific phone (usually a charger thats too strong) it can throw of the charge cycle. Thus, it can take like 30 minutes to drop 50% and then another 3hrs for the other 50% (this is just an example). If you're rooted, I highly recommend doing a full battery calibration.
Secondly, the Use Wireless Networks thing in the location isn't really a samsung thing, i think of it more as a google thing. I noticed that when its on, Google is always sending information back to itself, thus keeping the phone awake longer. Thats why if you go to your graph, it show that your phone is awake more often then it should be. I personally uncheck it, because if i ever need it, I just quickly switch on the gps. Then turn it off when im done.Thats my recommendation to you. Yesterday, I personally got a full 24hr usage out of my battery, and it wasn't even all that light. I texted most of the day, made a few calls, browsed the web, and listened to music for a few hours on the subway. Pretty moderate usage.

See, I'm not exactly unhappy with my battery life... but seeing what other folks around here are getting MAKES me a little unhappy.
I mean, I went to bed at... I'll say around two AM last night at 90% battery. My audio book player ran for thirty minutes after that; woke up at about eleven AM, 53%. NOTHING CLOSE to what you folks are getting. All of the big culprits I've heard mentioned have been checked out, and I just calibrated, so I dunno where else to go with this.

Does anybody see anything unusual about my battery life?
My screen has basically been off, yet I'm still losing weird amounts of battery. Based on the hours, I took my phone off the charger at 4pm Dec. 04 (16:00) and it died at 6am (06:00) Dec. 05. That gap in WiFi was my time at work.
Those bars you see in display right before WiFi get's turned on is me texting and Facebooking. Apparently I wasn't using Facebook enough for it to actually get a place in my battery usage.
And of course those two little bars in the red was my phone telling me that it's dying. Too bad I was sleep.
Ignore the rise after the fall. That's it charging of course.
Also, if you notice, my WiFi apparently wasn't using anything to get a place as well. Those are all the apps that were listed. Why isn't WiFi there?
I calibrated my battery twice already. I can calibrated it again since it fully died. Let me make sure I understand how to calibrate it.
ROM: ACS Syndicated Ice
Kernel: LoS Kernel
1) Phone charged to 100%
2) Phone dies
3) Charge phone to 100%
4) CWM and wipe battery stats
That's what I do to calibrate it.

Add a 5th step which is using the battery calibration app from the market. Also, uncheck wireless networks from location settings (huge battery hog). I assume that's probably your biggest problem. Then, if you are rooted, do what I did, which is get a root explorer and go into system>apps, and move the social hub.apk and media hub.apk to a folder on your SD. It will essentially uninstall it. Those 2 apps are battery hogs as well even if you have never used them. They will always run in the background. Try those and lemme know if it helped.

Wireless network location settings is also mainly used by Google to send them data about your usage. I noticed a significant decrease in battery life whenever this is checked. I would rather just turn on my GPS whenever I need it than keep this function on at all times. Its just not worth it in my book.

Best rom for battery? Current rom burns 1% per minute.

Currently using latest calk rom I get about 2 hours using my phone for browsing thr internet at home. When 3g is turned on it drains even faster.
It has always been like this. If the phone is set on idle without 3g and wifi it lasts about 10 hours.
also it takes about 3 to 4 hours to fully charge, i feel this is too long.
so any rom that might help me? is the battery faulty?

Blazer ROM

why are you using your phone to browse all day long ? use a pc or a tablet. its a phone not a desktop pc. plus put it into airplane mode and then turn wifi on, it disables the cel/data radios hence the battery last longer. If your phone takes 3-4 hours to charge from 0-100 something is wrong with it. turn if off and charge it, cuts down charging time A LOT !

That is ridiculous. But I've been using Blazer Rom for about 2 weeks now and I always get 30 hours+ battery life. I just got 3.8 and I hit over 40 hours just this weekend.

well, um, wow, those are some ... great suggestions...
you might have a bad batt, sure.
i would think it is likely something else though.
a few things off the top of my head.
is this on a "clean install"?
is there some app you have loaded that might be pinging/updating constantly? (I'm on the exact same rom, getting all day at least)
what modem are you on?
did you flash a custom kernel?
do you know how to take a screenshot of battery usage? show us what processes are eating it?

I get great battery life with Blazer 3.8.
Idk about 40 hours (WOW!) but I do get around 3-4%/hour battery drain so it's not bad at all.

Try re flashing the ROM. That sounds abnormally for ANY rom.

It could be a bad ROM (bad install, not the ROM itself), but don't presume that's the case.
Measuring whether the phone is draining appropriately is difficult to do when it's in active use (e.g., 2 hours of browsing) ; thus most people measure effective drain by measuring the drain rate when the phone is 'sleeping' -- though in some cases a bad app or bad install will prevent the phone from sleeping.
I would recommend charging the phone to full, leave all default radios on (GPS/Wifi/3g), and let it sit for an hour or two. If you're losing more than ~3-5%/hour, then you have a problem.
Tools you can use:
- CPU Spy - Will show you whether your phone is entering Sleep state or not
- Battery Monitor Widget Pro - will measure your mA drain rate; during sleep, you'd want it to be at least below 20mA, ideally below 10mA (note, this app requires a couple of charge/discharge cycles before its measurements are reliable).
- Better Battery Stats -- If you find your device is NOT sleeping, this will help you figure out what applications (including the kernel) may be preventing the device from sleeping.

Your point? I could kill my phone in 6 hours too, but why would I want to do that? I play games all the time when I'm out at work or just out in general and I still get over 24 hours of battery. I never use my phone when I'm at home, that's what I have my tv and computer for.

how long has it been since you flashed? Maybe it needs a few cycles to settle. Do you have any wake lock issues? get betterbatterystats app, free for xda members, to check for kernel or partial wake locks.
I'm on BlazerROM 3.7 and getting about 1% every 2 hours on idle. It took me a week to see the battery life i'm getting now. My wife is on calks 2.8.1, I don't know what shes getting but when she gets home from work, she's still around 50%. On stock, she was typically around 30% already.

how do you get betterbatterystats for free as an xda member?

I'm on blazers and i'm at 79% battery at the 7hr mark on battery.

I have seen this "mystery battery drain" problem in other threads. There is usually an app responsible. Try Watchdog, its not bad.
I also have heard that SD card or file errors can be responsible for the drain. Formatting the memory takes care of the problem. If it were me, I would format the memory, then run chkdsk (Windoze, or the equivalent in another OS) to mark bad sectors. In the case of internal memory, you will have to do that through the USB cable. Do so at your own risk, of course

Your point? I could kill my phone in 6 hours too, but why would I want to do that? I play games all the time when I'm out at work or just out in general and I still get over 24 hours of battery. I never use my phone when I'm at home, that's what I have my tv and computer for.

The point is you walk into someones situation and act as if their usage of the device on whatever rom your on is going to produce a parallel experience. One of the biggest factors no matter the rom is screen brightness. If you spend most of your time out doors the experience is completely different even with the same usage patterns otherwise. I love screen brightness personally, haptic feedback is nice too who cares about the battery when the experience is better?
I have games on the phone, GTA III, MC2/3, Dead Space, etc. I don't actually play them. I remote into my PC, browser the web. I have a TON of apps that use the phone idle/background. I keep steam and im+ pro going. I let TEP ping GPS data every 10 minutes. Weather widget, google voice, etc. I even have Samsung Apps installed with its oh so horrible push service that apparently rapes peoples batteries... cant say it hurts at all.
Today was a day for me where my boss was around so I couldn't use the device much and when i did it meant leaving things like a remote client on because I couldn't touch it to turn it off. 52% battery was left after 12 hours so it obviously was going to survive the 16 hours I am awake, going to sleep now so it would easily last 24 hours. But the battery being Li-Ion and me actually caring about it, its going on the charger. Tomorrow could be 30 and the next day will probably be 8 hours.
As far as the topic is progressing. Check your apps and your settings. Ive had battery life so bad the phone died on the charger. Same rom, same apps slightly different setup later and I am getting good to acceptable and that constant wake this guy is probably getting is gone.

If your using a lot of push apps, you're battery becomes nothing more than a decoration, lol. Apps like aim, kik, basically all the chat ones. Games like words with friends. The more apps you have checking for updates on top of heavy usage with kill your battery fairly efficiently

Which personally was part of the issue before on my setup. I still have them going again and battery life is decent. I mean Id want 16 hours out of a phone surely whatever my day is Ill have it on a charger by bed time.
I personally usually get 12 hours or more on days Im not using it constantly, 6 to 8 if I am using it every waking second. 24+ on days off. Haven't tried blazer in particular myself yet but Calks seems manageable even for demanding use.

FK23 rapid battery drain

First off I want to say I'm not a noob when it comes to flashing. I usually get 14-18 hours on a full charge with 3-4 hours screen time which seems to be the norm on e4gt roms. I haven't reinstalled any apps since flashing the FK23 stock leak and now a few days into the room settling I have almost 4 hours on a full charge and down to 9 percent left with almost 2 hours screen time. I have checked to see if my battery is swollen and it's not. The battery stops spinning immediately after I let go of it. Screen shots are attached and any insight would definitely be appreciated. I may have to go back to blu kuban since that's been giving me equivalent if not better batter life compared to FK23 stock

Did you use One click odin to flash this?
Try removing unneeded stock apps

No this is from the tar file flashed in Odin 1.85 I believe... Had no issues for a few days now it's going crazy...I didn't even restore my internal and external sd backups yet as I wanted to test a clean install first

I'm having rapid battery drain, too. I used the one-click no-data. I want to wipe everything and start over. Can I simply download and OC the data, or do I need to do something else, first?

As far as I know (devs correct me if I'm wrong) you can just use the OC restore that doesn't say no data... But I went the extra step and copied my entire internal and external to my pc for safe measures and so I could pick and choose what I wanted back on my phone. Then I cleared my internal and external sd before I even one clicked so it was already clean... I just wanted to make 100 percent sure everything was clean but that's just me

Im not having any issues. Let your phone go dead tonight and charge it completely to 100% while off. Do not interrupt it until complete. Since I started doing this on flashed roms I have been getting better battery performance.

I just did this while taking a nap and this is what I have so far after 100 percent charge and I restarted once to pull battery and look at it

Was it completely dead when you put it on charge? I don't know why this works for me, but every Rom I have ever flashed, unless something is wrong with it, gives me better battery life 3-5 days after I flash it. Some of the old-timers say a Rom has to settle for a few days, so maybe it helps do that quicker. If all else fails, reflash the Rom.

I gotta say that your drain seems pretty extreme! I myself am having slightly accelerated battery drain but its better than what I had on ICS. My best recommendation would be to use an app like ROM Toolbox or Titanium Backup to freeze apps and background processes you don't need. If that doesn't help you may need to look at other options.

^Thanked
I'm going to try installing GSAM and checking out what's going on in the background but as far as I can see nothing out of the ordinary is going on with the processes. On a side note when I took a look at my battery itself the sticker has pink X's on it. Not so sure if it's water damage per say but it may be condensation/humidity since I live in Florida. Looking into getting an extended battery as a replacement and any suggestions on the cheapest but most reliable battery to purchase would be helpful and I don't really mind if I have to have a larger back door on my phone. The cheapest I've found is a Trexcell with the back door for $16.99 free shipping. If anyone knows of anything better/cheaper please point me in the right direction.
Another issue I've been having is wifi will connect and reconnect uncontrollably whenever it feels like it, and the sprint connection optimizer was disabled since I Odin'd.

Ya GSAM is a must have. I run it on every one of my devices. I was also getting some irregular battery drain. Then I looked at what apps where keeping my device awake the most and found that hotmail app had a 4 hour wake lock! Ouch! I uninstalled that and setup the default email client to check my hotmail hoping this will resolve my issue. But I can tell you right now nothing else is keeping my device awake that long so in theory this should solve my issue. You may want to go through this same exercise. After a couple of hours of running GSAM looking at which apps are using the most power. Then switch your view to "Time help awake" and see if something has a wake lock holding your device awake.
Good luck

I re-read garwynn's instructions for the one-click and realize that I made a mistake going from ICS (Lightweight) to FK23 without a full wipe. I thought I was paying closer attention when flashing, but I screwed up. Thankfully, this should be easily fixable. I'm running the one-click restore and am optimistic things will be better.

Well after installing gsam I was able to see that after going from 77% to 15% in just over 4 hours with 1 hour screen time I noticed that media server had 293 wakelocks with 1 hour of time held awake...might have found the culprit...will keep you guys updated as im sure it will help a few...just wanted to update that I switched to Universe JB to see if it was just that tar...apparently it wasn't seeing just as much battery drain
Sent from my SPH-D710 using xda premium

And now I also figured out that the media server was not the only culprit. The battery seems to be the problem after numerous tests returning results that the battery was only a 1175 mah battery instead of what it should be 1800 mah. The battery does not spin so don't always judge by that test alone. After deciding to put my OG Epic 4G slider battery in and take it for a spin these are the results I have so far with 300 mah less (1500 total) here is the screen shots below from a full charge
*EDIT * I'm now running blu Kuban FI27 and tested also with the stock 1800mah battery still dies rapidly and WiFi still disconnects and reconnects randomly

Averaging 10% loss every hour
I am experiencing roughly 8-12%, so averaging around 10% loss every hour with moderate to slightly heavy use. Right now after 5 hours & 10 minutes i am at 50%. I have Facebook & an Exchange email synced and was on a phone call for over an hour, have been texting a bit and using email, the internet & Facebook. I have removed Sprint ID, which seems to run in the background along with Sprint radio, Nascar, Yahoo Stocks & News, so that may be helping a little. Overall I think that the battery performance has improved for me.

I was experiencing some pretty bad drain but after letting the kernel settle for a few days and disabling the location services, I can easily make it through the day

My batter time stinks!
I'm also getting 9% per hour battery drain. I have a Tasker profile running which turns off DATA when the screen is off. Most of the day, my phone has not been in use and I'm still getting battery drain. BetterBatteryStats shows that a process called "surfaceflinger" (Android System) has used the most followed by "googlequicksearchbox" followed by Gmail. Partial Wakelocks report says "signalCollector.Scanner has a count of 4844 and "LocationRecieverService" has a count of 3411 with "LocationReportingService" having a count of 5625. However, all of these combined only add up to 2% so I'm confused as to what is burning my battery.

Have u checked to make sure your battery isn't going bad? Take it out and try spinning it on a table on both sides if it spins like a top its starting to bulge, bulging battery = bad battery

Just did spin test as suggested. The battery did indeed spin like a top on both sides. Just ordered a replacement. Has anyone tried one of the "Gold" 2430mAh batteries made in Japan and being sold on Ebay from China?
