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??

Love The Phone but...Battery Rant

Hey Guys,
I am usually just a silent observer on the boards and try and gain knowledge from all these amazing developers but my experience last night has pushed me to vent. I live Atlanta, and a Vendor had offered us some suite tickets to the Falcons Ravens game. Of course I would take those. Knowing this phone does not get the best battery life, I made sure to have the phone fully charged before I departed. I left the office at 5pm with a full charge. Throughout the night I would send a txt here and there and take a photo, nothing too strenuous I thought. As the game was coming to an end I looked down and saw that the phone was already in the yellow, not terrible since it should last me till I get to the car. I’m not thrilled because this means the phone charge has only lasted 6 hrs. I get off the mass transit station and go for my car key…..and it’s not there. I check all my pockets to find nothing. I am now screwed. No car, no phone, no charger. To cut the story short, I had to find a payphone (needle in a haystack) and call collect to my father, who has the only spare key. Needless to say he was not too please coming down at 2 am to get me out of the jam. I am just so furious that the phone died so quickly on me. It seems if I ever go out at night, if I’m not near a charger, that phone is dead within hours. Sorry for the rant, but its just the one major flaw about this phone. My old Tilt would last a couple days ( I know I know, small screen low processor) But a solid day out of these phones would be nice.

Do you manage the battery consumption by turning off unneeded features such as Bluetooth and Wi-Fi? Have you set the screen timeout to a few seconds of idle time? The display is the biggest consumer of battery power. Finally, when I know I'll be away from a power source for more than 6 hours, I put a fully charged spare battery in my pocket.
FYI the Galaxy S has one of the best batteries for a smart phone. With careful use and battery management, I routinely get 16 hours before a yellow warning.

I had much of your same problem in the first few weeks of having the captivate, prompting me to go buy two extra batteries and a charger off ebay ($10). I feel that upgrading to cognition 2.2 and using the task manager to stop facebook and such from always updating has saved a lot of life, and my phone will last a day to a day and a half on a single charge, so long as I put it into flight mode at night. then I just shut the phone down, switch out batteries, and turn it back on.

I have the screen set at the lowest possible brightness (11%). When i am out i never have bluetooth or wifi on. Perhpas there was a runaway app that was draining the battery. I have never gotten 16 hrs though. My max is about 12, and thats if i dont make any phone calls. You start making calls, it just kills the battery life on my phone. I did use to have a spare battery on my tilt, i might have to do the same with this phone.

It's most likely because your phone is not sleeping when the screen is off.
Download the "Spare Parts" app or just enter *#*#4696#*#* in your dialer and check out the "Battery History". If the Running % is almost full (around 80%-100%) during a day's use, your phone isn't sleeping when the screen is off which means battery is draining. Give it a reboot when that happens, but the known cause I've found was that WiFi causes this issue.

Are you sure you weren't losing signal when you were in the arena? When you lose signal the phone constantly searches for a signal causing your battery you drain.
I know in arenas you don't get a strong signal...
Just a thought

Turn on airplane mod when ur not really using your phone..

I have a great battery life. Especially when not using HSUPA. Try deleting your battery stats.

I typically see 12 to15% per hour drain with constant use.... meaning display is on all the time and I am on internet, phone laying idle overnight... 1%/hr tops. I do have a nice signal at home though... ranges from –70 to –85 so the modem is not working hard at all.

[Q] Sudden Unexplained Increase in Battery Drain

Stock 2.3.6 with no changes to or updates in settings or installed software and I have been taking pretty good care of the battery in a 5 ½ month old Atrix 2 directly from Motorola and not previously used.
Several days ago battery drain when in standby when from approximately 0.5% per hour to 2.5 to 3% per hour. I did the following, although not necessarily in the order listed:
Bench tested battery at a battery shop – no problem found.
Verified settings and software. Cannot find anything that appears to be draining power, initiating communications, etc.
Pulled battery.
Hard data reset and tested drain rate with no additional software and had same problem as when normal software was installed.
Several deep cycles from 3% or less to full charge. In all cases mV appear in normal range of about 3542 mV at 3% to 4347 mV at 100%, again per Circle Battery Widget.
Broke down and called Motorola and although they tried to be more helpful than normal, the only suggestion that they could offer was to try another battery, which I do not currently possess and AT&T would not allow a short term lending even had they had one available.
99% of all charging is via stock wall charger, spot use of car adapter with appropriate specs when using GPS.
Typically recharge starting in range of 5-15% and charge to 100% as indicated by Circle Battery Widget.
Battery usage in standby shows about an even split between Cell Standby, Phone Idle and Bluetooth each about 32% of usage when in standby. Have always left Bluetooth on 24/7 except when charging and battery drain was only about 0.5% per hour. I even tested for several hours with bluetooth off and this did not affect the rapid drain.
Contacts are clean.
I even use Motorola USB cables both from my PC for data transfer and also with the wall charger.
No exposure to excessive heat/cold.
If anyone has any thoughts, I would greatly appreciate any help. Otherwise my next steps are to call Motorola back Sunday morning (U.S. time zones) and probably order an OEM battery from a reputable source allowing for U.S. holiday on Monday. Unsure how Motorola will treat this as warranty since 1) this phone is a replacement for Atrix 4G problems whose warranty would be expired, and, 2) batteries have weak warranty coverage anyway since so much of that is beyond their control.
Thanks

Same here recently.
My battery life has gotten a lot shorter (and cell reception worse). Most of my 'battery usage' is coming from cell stand-by.

Overcharged Battery
How long are you leaving the A2 on the charger? MTL you may have "overcharged" the battery, overloading the memory in the battery itself, therefore resulting in less usage time from a "fully charged" battery.
Typically, as a sales rep, I recommend my customers only charge their phone for the full 4-8 hours, when it is the FIRST time they charge their phone. typically after that, it takes only 2-2.5 hours to provide the phone with a full charge. Over charging will fry the memory and make the battery hold less charge and over a period of time eventually kill the battery, making you have to buy a new one.
P.S. If I am completely off base please let me know. Yes I am noob, but this info was actually part of my training courses so I'd love to tell them they're wrong. Hope I was helpful.

The phone electronics will not actually allow overcharging. you will have problems if you do overcharge it but you can't do that while it is in the phone.

Thanks but in addition to any designed protection against overcharging I also pull the phone off the charger as soon as practicable after hitting 100% per Circle Battery with the exception being when using GPS which means that the phone will charge very slowly to 100% and remain connected to the charger until the next stop in my trip. The phone charges more slowly on the car adapter because the screen is constantly on along with running GPS and music software and streaming music via bluetooth.
I also try to make sure that I always disconnect the charger before starting or turning off the vehicle's engine. It may not be necessary anymore but that is an old habit.

Happening to me recently, before the battery lasted very long, but the past few days I arrive at night with 20% left. I tried doing a factory reset but it still the same. Also, the "cell standby" is the biggest consumer? I don't know what does that mean...

As far as I know 'cell standby' is basically your phone searching for a signal.

Remove any app that u suspect. If u have installed battery indicator pro, that's the culprit. Same happened to my phone when i had battery indicator pro. Install juice defender ultimate. Works a bit. Clear off d ram and reboot

For what little it may be worth replacing the battery showed the same problem and motorola now admits that this might be a motherboard issue and wants me to send the device to them for repair. They had their level 3 contract tech support review what I had done for troubleshooting and they agreed that the above steps plus replacing the battery had exhausted all possible options that can be taken outside a repair depot.
Those with similar problems may want to do the same and finally call motorola.

Wonderful, I am on my 3rd Atrix 2. Returned two previous because of the sd card reader/compatibility problems. The third one I received hasn't had the problem but now I can't go more than 8 hours without the battery going dead.
Cell standby is normally over 33% and Phone idle is normally at 30% or higher.
This happens whether I leave wifi on all day or turn it off.
Stock 2.3.6
I work from home and I have 5 bar signal strength from my house so there is no reason for my phone to constantly be searching for network signal.

Still happening to me. Today I was talking with an AT&T representative via online chat, and they only tell you to disable background data, and set it to super saver mode. They didn't want to listen that the phone before lasted until midnight with the battery still green and that now it goes red. The guy said that the phone is supposed to last 8.5 hours, since that is the talk time. I tried to explain that the talk time didn't work like that, but no good.
Finally, I went to an AT&T store and inquired about the issue. Since I'm within the 1 year warranty they are going to send me a new battery. If that doesn't fix the problem they said they would change my phone.

P20 Sudden massive improvement in battery life

My wife has had the P20 from the week it was released in the UK. The battery life has been really poor, she is what I would consider a light user on a 4GB contract which she rarely troubles and with a tablet for use at home. She has taken to carrying a portable charger with her to make sure she got through the day. I had checked for any obvious drains, even turning off bluetooth, gps etc. But from a full charge in the morning, she would struggle to have any battery left by the evening, compared to me (a slightly heavier user) having about 40-50% left on my Samsung S9.
However at some point in the last week something has changed, she is suddenly going to bed with about 60-70% battery left.
Anyone else had similar? Has there been a significant update recently (to either the phone software or some other app)?
Craig

My mate 10 after a few updates, i actually use my phone to work, work 8 am to 6 pm get home and i forgot to charge the phone last night, woke up with 72% battery and was wondering if i should bother charging.

I think it has to do with the npu

I experienced the same after the last update. Before the update it would not last more than 4h sot with 1h voice calls. Now i can get 5h sot with 1.5h voice calls and still have like 30% remaining.

i have experienced increased temperature heat. dont know what is causing it.

Same here! But I just noticed it last night before going to bed (had it on full charge), woke up 8 hrs later and the battery only drained by 1% (only Wifi is on). Not even sure if the update was even downloaded without me knowing. But before this the battery for me was performing quite well, coming home in the evening with still 40-50% left.

Long term use reports

I got this watch in November 3+ years ago and still wear it daily. My battery life when I got it was an impressive 2+ days with the systems battery prediction also considered. After 3+ years, the battery seems to have got even better than it was when it was new. The last two charge cycles gave actual usage at 2 days, 16 hours with 19 hours remaining on non-battery saver mode estimation. I have screenshots going back to when i got it and even posted them on fb from time to time to chronicle them. I havent toned town my usage either, i still make calls on it on speakerphone as frequently as i ever had, still check as many messages, yada yada, and the battery life still persists. What is everyone else's experience?

I've had mine almost 3 years. I have the rotate your wrist & double tap to wakt up disabled, but BT is on all the time, along with heart rate check every 10 minutes. I usually get 3+ days battery life, and, I wear mine to bed to track sleep. The only time it is off, is between 5pm when I get home, and 10 pm when I go to bed.
