Is my battery life ok?
I think my battery is losing capacity or something is draining it a lot since few months ago i still could squeeze out of it about 3.5 hours screen on time, nowadays i get barely 2 hrs.
What also bugs me is that when i unplug it from the charger it loses top 10% very quickly. It goes from 99% to about 90% in just an hour or two in standby. Here are some screenshots, I don't see anything suspicious, still, I get less from it than before.
All screenshots are standby with everything shut, no sync, no internet on, nothing, it consumed 15% in about 9.5 hours and before, i got to lose about 1% in about 10 hours in standby.
Stock austrian rom 2.3.6. rooted.
Why are you still on GB?
lol. Because of the battery life and need fully working rom, but battery is very important to me. Tried stock ICS, after 2 weeks had to get back to GB cause of the battery.
Also, is there something wrong when battery monitor reports high kernel consumption? Sometimes in standby when there is more battery drain it shows high kernel consumption

Can you at least say is it normal for launcher to use about 10% of the battery? It's Holo launcher

Has anyone noticed their battery life seems shorter since the update ? I installed the official froyo update last night and it seems I'm running out of juice much quicker than before.
At first mine ran down faster. I ran it all the way down. Charged it. And ran it all the way down again and charged. It seems back to normal.
I didn't have any issues. Maybe you changed something else as well? Could always try a few recharge cycles and see if it stabilizes..
I was running the leaked 2.2 and I flashed to official 2.2. My battery life is almost double what it was. I can't complain one bit about battery life, although I have other gripes with the official Froyo release.
I'm with icepop on this one.. I was running the stock rogers rom pre-update and now with the official rogers 2.2 I'm getting at least double the use before having to charge again.
I'm having battery issues with the new stock Froyo. I lose a huge amount of juce when in standby. I thought I may have my widgets updating too often so I charged it up and put it into airplane mode last night. The phone lost about 1% per hour in airplane mode. IDK what is normal but that seems like a lot to me. I didn't have any apps running, except my alarm was set for the morning.
I have SystemPanel installed and my cpu load NEVER goes below 10 percent, even in airplane mode. I suspect this is a large part of the issue. In app history, system and system processes are always on the top of the list and are around 3% each. IDK what controls this or how to lower it. I would love some feedback from someone else with SystemPanel just to see how our numbers compare. Overall the battery life I'm experiencing is pretty terrible and a buddy of mine's Fascinate has much better battery life (hence something must be wrong somewhere). He and I were skiing all day over the weekend and when we got back to our cars, my phone was half dead and his had lost almost zero juice. This displeases me.
mine's was better actually. but i didnt stayon it for long
My initial results with 2.2 were very bad (10% drop per hour when idling). I reset the phone back to 2.1 then re-installed 2.2. This did not help. Now I did this again (2.1 then 2.2) but this time I have not re-installed my apps and have not rooted (yet). So far, battery life seems to be normal. I suspect that some of my applications might mis-behave when installed on 2.2. I am planning to add them slowly and watch the battery.
Not here, seems the same to me
Mine is terrible ! I don't know what it might have been on 2.1 as I upgraded fairly quickly. Essentially I charge all night and then disconnect from power at 6:30am and then by 4:30pm I'm out of juice (phone shuts off). Any ideas here? I'm not running anything extravegant (email only) and hardly make any calls.
Whenever you flash to a new ROM, wait for at least a week of normal usage before you judge the battery life. The reason is simple, your battery stats are reset after ROM flash and your new OS needs time to learn how your battery drains before it can give you accurate readings.
If you can't wait for that long, you need follow the battery calibration thread to force a manual calibration of the battery.
I'll give it a week and see how it is then. Definitely is draining much quicker now though. I think It acted similiarly when I first got the phone as well. If I recall correctly the batter life sucked when I first got it, but then a week or so seemed to get much better.
I did the manual battery recalibration (let it die, charge while off, turn on and bump charge...etc). Last night I lost about 2.5% of battery per hour while in standby. This seems improved since calibration but its still pretty terrible IMHO. Is this in line with the amount of drain other are getting or am I draining more than usual?

Running stock since purchasing the Captivate back in August, and so far battery life actually seems to be routinely as good if not better than 2.1. I must admit I didn't use my phone a huge amount yesterday (except for about an hour plus of downloading a bunch of wallpapers off Zedge for some ungodly reason lol), and after 18 hours of the phone being on I was still over 50% battery life left. 2.5% in standby doesn't sound like all is well - you must have something running in the background or similar issue. I have a live background, sync 5 e-mail accounts (granted, only one of those is every 15 minutes - the others are every thirty minutes, every hour, and once a day on two of them), and with light use I am getting over 40 hours with 2.2 so far (about in line with 2.1, but seems maybe just a little better). Heavy use I am dropping more like to the 12 - 18 hour mark (heavy use for me means the screen on more than off, actively playing games or using apps, large amounts of texting, etc. Solid game playing I haven't figured out a drain yet, but on some games it seems like I can drop almost the whole battery in close to 10 hours). At your rate of 2.5% per hour in standby you would only make it forty hours without even using the phone. I have been using mine just a little this morning (FB check, logging in to one of the desktops at work remotely to make some changes, live background running, WiFi sleep policy is set to when screen is off, but to be honest that is about it) and I haven't moved off the 100% mark yet and the phone has been unplugged over an hour and a half.
All that said though, as other users have stated you might want to give it a little more time for the system to recalibrate the battery usage. I would definitely check your processor usage though regularly to see if anything seems 'off'. One thing that caused me problems was that my SNS service would be running but then would get stuck in a pattern of 'Restarting' - would drain my battery rapidly.
It has been said that bettery drain is not linear. First 5% goes real fast. So, you need to judget the average over a day of use, not first hour or so. I'm still in first week of ROM flashing. So I can't confirm anything yet.

I am getting a very short life out of my battery. I run firefly 2.3 and with everything off i am at 50% after about 4 hours. any ideas please.
Samsung Captivate
Firefly 2.3
speedmod k13b-500hz #54
I'm not too sure.
I almost get 1% a little bit less than an hour 45~50 mins at idle.
This is no data and nothing on.
But once wifi is on, it ate about 15~20% in under 30 mins. This is with browser open and msn
I suppose data would be around the same if not a bit less or more underload.
I suggest do all those things that increase battery life ppl suggest on the stickies.
4 hours doesn't meant much without more info. You can have your phone on for 3 hours and been surfing the net or playing games the whole time so I'd expect your battery to be nearly drained.
How long is your phone on for?
What % is the display using up your battery?
How long has your screen been on?
After display what's next for battery usage?

I would go through all the basics:
- Charge to 100%, wipe back to stock and do a fresh install
- Charge the battery to full again, do all the basics to get a legitimate read (plug/replug, wipe battery stats)
- Check your about phone settings and look at battery use, check for battery hogs.
- Check to see if you are in an area with poor signal. I lose signal if I'm indoors where I'm at so I turn the phone to flight mode. If I don't it eats about 15% of my battery an hour.
I get consistently good battery life with my captivate/FF2.3, so I'm betting it comes down to a faulty install or battery measures.
I've also noticed this after I upgraded to 2.3 (from stock Rogers captivate). My battery used to be at maybe 70% at the end of the day, now it is at 20%.
I just checked it, and it is reporting 93% after 2 hours. The display has only been on for 2 minutes but has used 48% of the battery.
I have the display set to the lowest setting, no gps, no wireless, limited background apps.
ok i turned everything off and put into flight mode and set the screen to turn off after 15 seconds brightness set to the lowest point on the slider and starting out at 99% on my battery, after letting it sit for exactly one hour with no use at all i turned it back on and it was at 83%. how did it eat 16% doing nothing. I also did like you said with the reflashing and clearing of the battery info and still get the same results. do you think it may be a bad battery.

I'm getting great battery life with Firefly 2.4(no mods added) with WiFi on 24/7...might wanna upgrade, it is so easy with the on-board download and upgrade built in!
I made the mistake of flashing when I wasn't at 100% battery not knowing how much of a pain it was to calibrate the damn thing. I did however realize that after a couple of full charge/discharge cycles my battery life improved. FF 2.4 seems to have better battery life, but I haven't had it on the phone long enough to say for sure.

My first charge on 2.4 never displayed "FULL" in the top left like I'm used to seeing. I bump charged just once and cleared stats. Still couldn't get that "FULL" up there.
That said, my batt lasted 2 full days on the charge with minimal usage (3 or 4 calls, a few short youtube videos, 4 or 5 rounds of Angry Birds, otherwise with display off sitting by my chair on my wifi).
That seems like ridiculous good standby to me... perhaps too good. I'm afraid I might be badly overcharging my battery, so I let it drain until it I couldn't turn it on and it's back on the charger. I'm hoping I'll see a "FULL" up there this time. On the other hand, I sure could get used to that kind of standby time...
There is a Q&A thread in the Q&A forums please use those instead of opening a new one.
Hey folks,
i am using Oodie's 2.7.6 MIUI rom and the air kernel v4.4. i am experiencing a rather annoying battery drain. the phone has been running ~15h on battery and is at 63%, however I haven't done anything with it except for checking FB once.
The phone is UC and UV (100-880mhz, voltage all down at least 25mv). according to the battery monitor it seems to be "android OS". how can i figure out which process exactly keeps on draining the battery?
push notification is active for three apps (google mail, kakaotalk - sth like whatsapp, facebook).
37% in 15 hours is roughly 2-3% an hour. You're probably not going to get better battery than that since that adds up to roughly 40 hours of standby which is very good batter life. Android OS is at the top of the list because nothing else is using power (it's a relative statistic).
Most definitely. From the looks of it, you barely even used your phone.
this is exactly my question. the battery drain wasn't this bad before. Even with slight to normal use i could go around 30+ hours without recharging. now the battery is done in the same time without any usage
i had that on quite a few ICS ROMs myself... turning auto rotate off fixed it for me, maybe it does the same for you
I had this problem before I flashed the ROM, but that was several years ago so I can't compare between now and then, but it is clear that my device drains battery abnormally fast. I would say it lasts about 2.30 hours and it gets very hot over time.
To give a perspective, the miscellaneous battery drain went from 33% to 71%
Granted, I was installing new apps during that time, but I still don't see why it should drain so much, especially when it is miscellaneous that drains the most.
Buddy! You got a rom on there for just 4 hours! Way too soon to tell anything about battery usage and forget the on board battery statistics. Might as well read your coffee grounds...
Plus, tons of stuff is going on in the background after flashing a rom, indexing is one of them, AND Katshmallow is overclocked which makes the tablet run on the hot side anyway and eats battery. That's the price to pay for speed.....
Run it for a week, install Battery Battery Stats, maybe Wakelock Detector too, then we can talk about battery drain....
This is my first time owning a tablet so I don't know how battery life works here.
At 29% from 100%, I have 17h 29m, SOT 3h 14m, wifi 17h 29m, fallout shelter 40m, YouTube 22m, and some minutes on fb, etc.
Does my battery life ok or not? Thanks guys
Btw I'm on 6.0.1 v1.4 rooted, stock rom and kernel.
Seems a little low sot the tablet is generally going to get 5 or 6 sot hours
It depends on screen brightness! WiFi also takes more than it shows in the stats!
In the beginning, the battery drains a lil faster. But after some recharge cycles it last longer and even recharges faster.

My screen brightness is like 25-30% only everytime. Power plan is Max. Yeah the battery charges faster now, i get like 1500mA-3100mA, most of the time is 3100mA using LG G4 charger. In recharge cycle, do I need it to charge it to 100 then down to 0%? Thanks
Yeah, max performance takes most juice. Really no need for it until a heavy game lags, which so far never happened. I played Godfire with high rendering and it's smooth.
I usually recharge to 100% when the battery is at 5% or below. I've battery saver turn on automatically at 5% so I know when to recharge. At 2 to 1% the Shield makes an auto shutdown. Some say, it's not so healthy for the battery to drain it 0% every time. I dunno.
Okay, just found out that my Shield takes about ~5% per day when being idle. Hence, you'd get 20 days standby. Airplane mode on, WiFi off, processor mode: optimized!
