battery acting weird or is it normal??

ok so i basically went 2 days with no charge on my TP
first day i used it and it held the charge of 100%, while i was at school i send a couple of sms messages and checked my phone every 30 mins to an hour and it still shows full charge then at the end of school(7 hours) i started using SMS again and it went down to 99%, it started to drop every time i text someone or just browse my phone, then it stopped at 92% for at least an hour then as i recieved twitter and weather updates it never moved then when i shut off data connection, everytime i check my phone battery keeps dropping constantly until 85% then it was stuck
at the end of the day my battery was at 75%, woke up 6 hours later and it was at 69%
on day 2 i started to use my music player for like one song which was about 6 mins with screen off, battery dropped from 69% to 56%
used opera browser on EDGE(since its got the best reception in the area) used it for at least 30 mins and it dropped from 56% to 32%
does this show my battery is not calibrated?? is it time to get a new battery?? or is this a normal behavior??
plz help
btw i was on EDGE Network the whole 2 days
and info is on my signature

Its not ideal, and letting it have a couple of full charge/discharge cycles might help it read slightly more consistantly. But other than that its doesnt seem too abnormal for a battery discharge. I guess its not showing you a linear discharge as you are spiking the load for a short(ish) period of time, then allowing the battery to basically rest between "hits".
As for a new battery - you got 2 days usage out of it, so unless these days were unusually light usage, i wouldnt worry about a new battery.

I think it's normal, i use wifi and music player allot so i charge it everyday just to be sure i have enough, internet is really eating battery. even if only updating still takes much. i figured out that if u r not using those 2 functions battery keeps full MUCH longer.

Another battery life thread...

Is there any way to get this thing to last over 10 hours with moderate/medium usage? I mean I hate to compare, but I was able to use my iphone 4 hard periodically through the day and be at 40% around midnight, but I have to stay using my captivate very lightly after about 10pm, and I usually unplug around 12 to 1pm..
I don't want to have to sacrifice majors perks of why I switched to android just to get a full day out of it. I've tried a lot of the suggestions I'm the forums, but nothing makes a notice difference, or makes it a fame changer as to where I'll get a full day of moderate internet/media usage
Thanks in advance.

Have you tried draining and recharging the battery as other threads have suggested? I usually unplug around 9-10am and I don't get battery warning until near midnight or later.

I keep seeing people complain about the battery life constantly.. but to me coming from my bb bold it seems that the battery is lasting way longer then i expected.. first couple charges i let the phone drain down till it shut off, and then charged it 100%.. its still new to me so im constantly playing with it and changing the menus around.. i try to make sure almost everything is closed when im not using it.. cause im sure that eats battery life..

I did it once, but I booted back up the phone a few minutes after I plugged it in, will leaving it off while it does a full 100% charge noticeably increase battery life?

Do you have widgets updating frequently? How frequently? Maybe just too many updating widgets. I get about 18 hours with the screen on for 4.

18 hours also
I'm getting 16-18 hours of use with about 4-5 hours of screen time. Better than expected.

Today I used my phone as much as I used my iPhone 4 on a regular basis. My phone has been off the charger for just over 12 hours and I have 70% of my battery left.

I'm around that too, I use a black background to save power and I have about 5-6 hours of screen time and I watch a movie on it every day (treadmill at the gym)
I only get low battery around midnight

I use advanced task killer and set it to when the screen is off to kill apps, aggressive mode, I can go about 20hrs before I need to recharge. 5-6hrs screen time.

One thing about android is it has true multitasking. Combined with some apps which do NOT close properly and continue to use up CPU this can drain your batter very fast.
In the battery Info your TimeSpentAwake should be ~ the same as Display on time. If not something is not closing properly. Use OSMonitor to check which program it is and either uninstall it or make sure to kill it with task killer after using.
I have the M110S (Korean Galaxy S - I get 16-18 Hrs with moderate use, but M110S comes w/ 2 batteries so i just swap )

Yeah based on people who are getting good battery life mine is absolutely terrible. I am on my fourth full discharge. I have had my phone off the charger for 2 hours and I'm already at 87 percent. I listened to about 45 minutes of cached slacker radio and like 2 posts on xda app

Just to comment on my battery life. I got my phone saturday (2.5 days ago) and its been on the whole time with medium usage. When I got the phone the pamphlet inside said "fully charge before you turn on" and thats what I did. My battery is at 41% and the only time that I have charged it since is when I am connecting it to my PC for a very short amount of time. I have had great battery life so it is possible. I am very impressed with it.

Yes...my battery life has been good...
Screen brightness all the way down (auto brightness off) *same for the browser brightness
Screen timeout 15 secs (annoying sometimes so maybe 30 secs)
No window animations
Power saving mode off (no point in having the lcd adjust if its already as low as it will go)
I also dont have any widgets that update in the background, however i'd imagine one or two wouldnt affect the battery much
These settings have worked out for me and i use the phone moderately with 2 hourly updating email accounts.....

Battery life for me has been decent. I consider myself a moderate user and I can go from 7:30am till I go to bed at night without dying, but its close. Coming from an iPhone 2G, where with the same usage I could get 2-3 days on one charge, its a little disappointing. But it is what it is I guess. I have heard horror stories of EVO's only going 4-6 hours on a full charge, thats ridiculous.
But what gets me is all this nonsense about fully discharging before charging back up every time. These are Li-ion batteries, they are not Ni-cads, they will not get a "memory" if you dont fully discharge every time. Yes, its good the very first time, to fully charge it before using it, but after that, it doesnt really matter.
Also, one more thing I noticed. The phone will stop charging the battery the second its fully charged. So if your phone reaches 100% charge at like 2am, it stops charging at 2am and you are then going from 2am till whenever you take it off charge in the morning. I noticed this the other day. As soon as the phone told me it was fully charged, the battery icon turned into a normal battery icon even though it was still plugged in. So its possible that the phone is going for 4, 5, 6 hours off charge before you even wake up. What I do to make sure I'm at 100% when I leave, is when I get up I unplug it, use it for a minute then put back on charge while showering. Then when I leave for work, I know its fully charged at 100%.

I guess I'll be switching out phones at Best Buy today as well. Phone keeps losing 30-40% overnight (more like 5 hours max since I'm a night owl) even with everything turned off. When I do get back to a 90% charge before I leave for work at 8am, I'm usually left with 30-40% by 5pm after 15 texts or so and a few emails.

I am fairly sure all new batteries have a chip in them that regulates the power. So you HAVE to run it down to 0-5% and charge it back too 100% several times before the battery is even calibrated for use. That has to be why its 50/50 battery sucks battery is great, just let it drain and charge it again.

battery life simply not acceptable
Hey guys,
I know many people post on battery life.
Here is my situation.
I do not care about beauty, but functionality is a must.
I am in the hospital from ca 6am to 7Pm and I have Q4 call meaning every fourth night its to midnight. That is simply a fact of my life.
My requirement:
I need my phone to last for this duration without recharge.
1.)
I don't need or use widgets
2.)
I don't need or use a wallpaper other than a solid black background.
I do need and use:
the GSM radio and wifi both need to run the entire time and reception is what it is.
My applications of use:
merck manual, dynamed, epocrates the usual in my boat.
I really really want to use this phone, but battery life wise only my blackberry with extended battery and my iphone 4 can hack it.
If any of you have any suggestions on what I could do plz let me know. My last resort is carrying two batteries, but that would frankly be admitting that this phone is inferior to the iphone 4 which can hack a 20 hour usage day in my setting.
(I absolutely cannot turn wifi or 3G off both must run)
I am open to all suggestions including the task killr controversy or anything else constructive one may have. Any extended size batteries out there for the captivate?
Thanks a bunch in advance.
(Having had my secretary spend 4 hours rooting the phone and sideloading Merck manual is a testament to the pathetic entity that is AT&T by the way. If you have professional apps from an institutional subscription you cannot download the software from the market...)
PS: My secretary is not exactly a hacker so forgive the 4 hour timeframe.

I consider myself to be a heavy user!! I like to text, browse the web, listen to music (either from my own files or streaming,) check email and comment on facebook all throughout the day. I did that perfectly fine with my Bold 9700, that battery lasted a full day or more.
I had an iPhone 4 and my battery would not last my 8 hour work shift!! I either had a bad battery or who knows what was going on with that phone. I didn't even leave the apps running...the phone was nice, but that battery killed it for me. I don't understand how some people got a full day out of it.
On the Captivate the most I have gotten has been around 10 hours of use and that's not even using it how I normally like to. I stop charging it at 8:30 and my battery is 100% around 10am I'm already in my low 90's or upper 80's. I don't have any widgets updating, I have a black wallpaper, I don't have the haptic feedback on, and I sync email hourly.
Could my battery be bad?? How can some of you manage to get 16 or so hours out of it??

BATTERY Performance / Expectations

I'm just wondering if some other Sensation owners can chime in with their battery stats. I've had the phone for a couple of days now, and with a few battery cycles behind me, I'm still concerned. I do understand the "new toy factor" of using a new gadget much more frequently than normal, but what specifically concerns me is the amount of juice the display is using. With push email on, twitter sync on, auto brightness on, and mostly indoor use, I am finding that I can't get more than 3 hours of Display On time. At the moment I have the following stats:
17% Battery Remaining
9h 5m 9s on battery
Display: 80% (Time on 2h 7m 31s)
Cell standby: 8%
Phone idle: 5%
Wi-Fi: 5%
Maps: 2%
Usage has consisted of some light web browsing, just a few minutes of phone calls, lots of texting / email, and general playing. At the moment, I can barely make it to the afternoon, let alone a full day. Is this comparable to what most of you are seeing or do I have a bad battery? Coming from a Samsung Galaxy S I was hoping for better performance but so far this is far worse ( I used to get 5+ hours of Display On time )..
Thx..

45% remaining
On battery 6 hours
Display on 2hr 10min
Display 85%
WiFi 6%
Cell standby 6%
Phone idle 3%
Comparable to my DHD I'd say, possibly a bit better. Custom roms did improve that though
Funny thing is my girlfriends galaxy s has shocking battery drain, particularly in standby. She's currently on Darkys ROM and I've given up trying to figure why she can never last a day with her phone.

Coming from a G2 and this phone seems to be much worse. At work I would make it through the afternoon with very minimal usage mostly idle and checking my email on it 8-10 times and have 80%+ left over when I left the office after 9 hours off the charger. Even mostly idle I'm at 50-60% during the same timespan with a 20% bigger battery. Yesterday I was @ 95% and used the GPS for 30 minutes and it dropped the battery down to 60% in that small time period.

My batyery sucks big time... I trained it once - didnt do anything. Still get about 8 hrs between 7am and 8pm. Light to moderate usage :-(
Maybe i should look into finding a bigger battery

I get about 14-17 hours, depending on usage. I'll post my stats later today as I'm at 100% right now.

I would disable htc hub from syncing. It syncs every few minutes and drains the hell out of the battery. I also disable always on mobile data and that helps save the battery when my phone is idle but things that you auto sync might have problems. My .02.

This is pretty much my usage.
I can get over 24 hours pretty easily if i'm only using it for a phone call here or there. This is with Wifi turned on(and wifi calling on), auto-brightness, and auto-synching set to different intervals. Exchange email is set to every 15 mins, google set to push, FB is manual, weather is set to once a day.
If I'm using it pretty heavy, browsing the web, playing a game or two(peggle & plants vs zombies), I'll get typically around 12-14 hours.

For the first few days the battery life in my brand new Sensation sucked too. I was getting maybe 8-9 hours of moderate usage before having to plug it in to recharge.
On Friday night (June 24th), I did a full factory reset through the bootloader, installed Juice Defender and set it on Aggressive setting, and charged it overnight for about 8 hours while the phone was turned off. Yesterday (Saturday, June 25th) after over 18 hours of moderate use, which included many phone calls, emails, some texting, browsing, playing with the phone, and even a little bit of Stupid Zombies, the battery was still at 42%!!!
I charged it overnight again for 8 hours. So far today, after 3.5 hours of HEAVY usage, the battery is at 93%. I am beginning to like this a lot!

Email auto-sync, BT on at all times, some internet radio streaming today and still at 91%. It's been off the charge for 3 hours now. I think that's pretty good compared to my HD2.

I have been very happy with the battery life so far, its better than the battery life was on the MyTouch 4G I had. Can go a whole day no problem, MyTouch 4G couldn't make it a day....

To all you guys that are getting phenomenal battery life, could you check your battery stats and tell us your display usage?
Thx

I will post battery stats later today but battery life has not been as good as I hoped. Compared to the G2x I'm getting worse battery life. Then again, it's too to compare a device that is running a custom rom versus stock.

So with 48% battery left your display had been on for over 3 hours? That is excellent.. Definitely something wrong with my battery if that is the case.

Yup. thats what i read... maybe i should tell you what I did when I got the HTC Ssensation...
I used it and set it up on that batt level that came out of the box... till it switched off... kept if off and charged it the whole night.. about 7 hours.. unplugged.. turned the phone back on.. used it again the whole day and brought the battery level to about 19%.. turned it off.. charged it again full for about 7 hours... and now i am using it as normal!!
EDIT::: hahahahahhahahahahahaha.. no wonder... I am sorry.. its a typo.. 2 hour and 11 Mins.. well now 18 mins!!!
Still quite decent I think.. with the usage!!!

My battery sucked too but its doing much better (ibwas not worried because the same happened to my nexus one). Always moderatevuse and I get about 16 hours of use and still have about 40% left.
I have auto sync on, wifi off, screen brightness on about 60%.
Sent from my HTC Sensation 4G using XDA App

This is probably the longest lasting device I've used in a while. My G2X would get me about 11 hours with moderate use but my Sensation will last close to 16 hours with moderate use.
The only thing I have syncing is my Gmail account and calendar. I turned off everything else including weather. I also never keep my display set to automatic since that's just another piece of hardware that constantly has to work. Unless I'm in direct sunlight, my display stays at 50%.

Just got a Galaxy S3 - 17% battery after 12 hours "use"

Basically as the title says, I've bought a "refurbished" one, but I'm not sure whether it's faulty, or whether this is just the average battery life of one of these things!
Woke up at 6am, I used it for about 30 mins this morning on facebook/ebay/bbc news through wifi. Send about 20 txt messages, 10 minutes on the phone. ANother 30 mins browsing/facebook on my lunch break. 12 hours later it's sitting at 17 hours battery life. And it's been on power save mode the WHOLE time. Is this just something I'm going to need to get used to or is mine just a dud?
LOVE the phone otherwise though

whats youre screen on time? do you keep data and stuff on when not in use?

The first couple of days it will be bad while it builds up cache. It will get better. You can try rooting it and putting a custom kernel in to make it last even longer.

Note 10+ battery drain

I've had this phone for two weeks now and the past few days every time I charge it to 100 it instantly drops to 99 after 2-3min of use. I'm not running any heavy programs either if I just have the screen on it will drop. In the screenshot below I had 13min of use and it went down to 98. Is this happening to anyone else? I don't have power saver mode on.

Seems to be just about right

If you're not getting good enough screen on time and did factory resets already, try reflashing the system. It worked for me.

Mine does the same exact thing. My note 9 never had this issue and I'm only seeing 3 to 3 1/2 hours on screen time..
My samsung SM-N975U battery averages 1d 0h 0m (19h 50m 0s active usage) on a single charge.

My note 10+ goes from 100 to 97 in about 5 minutes. Current situation -
upload
The last thing I'll complain about is going from 100% to 97% in 5 minutes with this type of battery life.

I am in a situation where it feels like its draining faster then it should, but Im also using it more than I should, so I dont know if a phone issue or a me issue. Im gonna do a reset to see if the results remind.

I realized that the Secret for obtaining high amounts of battery life (screen in time) is if you consistently use the phone.I found that I can easily get 10 hours if I'm constantly using the phone to the point where the screen is on for 10 hours. The second I put the phone to sleep and I don't use it as much is when I start heading 6 to 8 hours of screen on time. It's weird how they've implemented this but,
I now just use my device without even concerning myself with the battery life for screen on time because it doesn't really matter. In the back of my mind I know I could get 10 hours if I actually spent that amount of time on my device with the screen on. When it comes to regular usage 6-8 hours on a device that lasts a day and a half sometimes almost 2 days I don't think it's anything to complain about

The problem is that your phone like mine must have came with 4300 or less mAh ... Most likely less ... Mine has 4280 mAh I am very pissed at Samsung for that since my hauwei p30 pro phone have almost 4800 mAh so it spends 8 hours in 100 percent until it starts to decrease the battery that is why so many fear hauwei I guess it was my first phone from then and it's amazing how it is superior to anything I have ever seen before ...

Ya me too how solve battery drain issues

I have a issue with regards to the battery where if the battery is reaches 10% , then from 10 to 0% drains within 1min. Any idea how to fix this or issue with the battery?
