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.

CM7 and Battery Woes

I will tell ya, I have been extremely disappointed by my new MT4G's battery since I got it just before Christmas.
If I unplug at 7am to work (I work at home) I can bring it in, not use it all morning, and by 2 pm I was looking at 70% battery with almost zero use? If I used the phone at all, I'd be looking at charging it by 3 pm.
Needless to say, if I went to sleep, I HAD to have the thing plugged in to charge as it was draining very fast while doing nothing.
Never really could figure out why, but yesterday mid day I installed Cyanogenmod 7 on a full charge and it's 7:53 am today (I didn't plug my phone in to charge last night) and I'm still at 50%.
No juice defender, nothing, didn't plug it in (I forgot, and when that usually happens my alarm doesn't go off because it's dead).
If you're having massive battery issues.......try CM7...I had tried everything on glacier roms to get better life. My phone would randomly wake up...now it doesn't.
Anyone have a similar experience moving to CM Roms?

That sounds like it might be worth checking out, but I will wait until the official cm7 release is out.
I am using setcpu to underclock my phone while the display is off. I unplug at around 8 AM, and I can get to 1 or 2 pm with 98-99% of my battery remaining with no use. I went to sleep last night around 12 with 29% left, and I woke up at around 9 with about 27% left. I should also add that I spent a pretty solid amount of time yesterday browsing the internet and playing angry birds, so I was pretty pumped to have that kind of battery left at the end of the day.

what's weird is I could play a game a lot, or do something considered heavy use and I really wouldn't get a ton of battery drain. It would drain a lot when I seemingly wouldn't do anything.
I too have setCPU profiles, and had to use JuiceDefender to even make it to the evening with light use.
I've had 4 different Android phones now, this was the only one that acted like this (all were battery hogs, but nothing on this level...Droid, N1, Vibrant, MT4G)
as far as waiting on CM7.....I didn't see any reason to wait. Everything seems to work very great with the newest builds and I don't really have many/any issues.
Was worth the switch for me to fix the battery issues with the stock I was having.
I STILL think it had to be a wake issue...ie, the phone waking a bunch during the night and turning the screen on/processes on. I haven't noticed CM7 randomly wake my phone once since I changed.
of course, it could be something kernel related too

what is your per hour average battery drain?

Almost a month since purchasing (Amazon return window coming up fast). Here's my experience given that I walked right into this battery-gate issue.
Disclaimer: I'm a heavy user. I get A LOT of email notifications, WhatsApp and keep the screen fairly bright (never less than 7 out of 10). It has Verizon LTE service. Verizon said this would not affect my battery life....
Week one. On a full charge I could only get about 5 hours. Off the charger 9 am and by 2pm it was back on the charger for a one hour re-charge that got me home until it was back on the charger for the night.
I had to purchase a second charger for my desk during the day. I picked up a third for $8 just to keep in my bag for when on the go.
Week 2. Same 20% drain per hour.
Week 3. I switched off diagnostic notifications, and switched from vibrate alerts to sound alerts. Big improvement. I went from 5 hours to about 9 hours. Battery drain is now 11% per hour.
Zero Lemon needs to make an S3 case...
And it needs a fast charging port. A Battery this small would charge quickly with a cord. 2 hours for 0% to 90% is pretty ridiculous in this era. My Note 3 charged to 100% in an hour 4 years ago.. And yes I know it's for waterproofing but other makers like Garmin and Polar use charging ports with waterproof gaskets.

I was getting about 2 to 3 percent per hour until a few days ago when the battery drain bug hit. At that time, it was almost 12% per hour.
I did a factory reset and I'm sitting at about 1.6 to 2 percent per hour.

I get about 1-2% but I don't need the fitness tracking stuff so i usually have Samsung health disabled and AOD off but location on and wake gestures on. I also have the diagnostic option off since the day I got it. I read somewhere the current battery bug can be averted by turning the diagnostic option off. I get 20+ emails a day and about 30+ texts and WhatsApp each. So I generally use my watch for texts, WhatsApp, emails, weather and Samsung Pay

With AOD ON and use for many things : cheklist, note, memo, notification, alarm, timer, stopwatch.... I have average drain of 3.5% at 4.5% by hour. I'm happy when I have 3.5% but it grow quicly to 4%-4.5% if I use a little. Just but can live with this.

For those who have serious battery drain on v3.0.0.2 (and even have broken sensors such as heart rate detection like me) can go for repair, if still covered by warranty.
I have recently the same behavior as described by many after upgraded to v3.0.0.2, battery drain 20%/hr and it become worse when I found out wake up gesture is not working at all, so is the heart rate sensor as well as steps tracker.
I hesitated whether to send it back to repair, but in the end so glad I did, it only took 1 day and they informed me they have changed the motherboard and replace with new battery (as I told them about bad battery drain issue as well). And guess what, I got back my gear s3 frontier with everything working but on old enough firmware 2.3.2.3 (which is working pretty good, just that battery usage around 5%/hr not that great).
After that I decided to take the risk to upgrade my firmware to 3.0.0.2 again, and whoa, everything still works perfect and battery drain has gone! Battery usage is now around 1%/hour which is acceptable I think.

Happy 3rd birthday

I've had this watch for three years, this month (March 2021). I've not had ONE problem with it in that 3 year time frame. I've paired it with 3 different (non Samsung) phones without any issue. Battery life is EXCELLENT!
I wear it at night, which is how I found out I had sleep apnea! My sleep patterns were all over the place. After talking to a doctor and having a sleep study, I've been on a CPAP for 2 years. Sleep patterns are much better.
I'm on day 5 of battery, with 18% left! I turn it off around 5:30 when I arrive from work, then it stays on from around 10pm until 5:30 the next evening. Rotate to wake & tap to wake are disabled. HR monitor checks every 10 minutes. I love this watch and if the battery finally starts to wear out, I'm just going to find another battery and replace it. Rugged and DEPENDABLE.
