Battery life on first charge - Galaxy S II Q&A, Help & Troubleshooting

Just received my set today, and the battery indicator was half full when I put it on first charge
Finished to full within 1.5 hours, and I used it to surf the net for about.. 5 minutes? The battery dropped to 86%
Is this normal?
Android OS usage was 6% though... no sign of the battery drain bug.. Yet!

That happens to me too. The first 10% seems to drop real quick

On your first charge? How about subsequent charges?
I did not have a chance to load test the battery... Because of the stupid camera defect, it is now in the service centre...

No its not normal by any standards .
jje

Surely it'll get better on subsequent charges?
Does leaving GPS Satelites 'on' have anything to do with it even if Google maps is not on?

I'd give it at least a few days of normal use to see how it goes. I've had mine for a couple of weeks and the battery life has definitely gotten better. Now I easily get a full day out of it and have 20 - 40% charge left by the time I plug it in at night depending on usage.

give it two or three weeks and you should notice significantly better battery life. mine certainly improved.

Charging

I am wondering whether the charging methods make a difference to battery life?
How do you charge your battery, and also your initial charge from new?
This is the first phone I've had that I didn't leave the initial charge on all night 16 hours initial as recommended by most phone manufacturers, and I just took it off after a few hours when it was charged up. Do you think that affects the performance of the battery? I've never charged it for more than a few hours. The main reason I don't leave it on all night is because it gets really hot, so when it goes green light, it's done for me
Do any of you let it run out past the amber warning colour as a completely flat battery is probably better to charge?
All my other phones were left on charge all night, every night, but they weren't this type of phone.... and in truth, it makes no difference whatsoever to the battery. The Motos also needed charging every day
Stunning work guys, 56 views by people I can only assume own the Hero, and nobody wants to divulge their dirty secrets about battery charging... Thanks anyway
Just look around google for Li-ion recharging, there is plenty of resources to read up on when trying to keep battery life at a maximum.

probably because the hero is so new that nobody can tell anything about the battery life? and i don't suppose any of the 56 people has two heros and did the experiment of charging one full and the other for 16 hours, only to use them in the same manner afterwards and count battery life... ?

Yeh, that wasn't actually my point, but thanks anyway!
112 now...
I was wondering how many people just got the phone, and charged it 16 hours initially or couple of hours and go, and do they leave on all night despite it getting hot.
Not hard...
You should charge it until it is fully charged but not leave it on charge extensively - excess heat may cause the battery life to reduce (although I wouldn't know how much degradation this would cause). It is probably ok every once in a while to leave it on charge overnight, in theory the phone should have circuits to protect against overcharging it anyway. 2 hours is about right for a charge cycle. You should charge it when the phone advises to do so - 15% or less charge. The Lithium Ion battery will only recharge cycle effectively a minimum of 300 times but I would estimate conservatively that is the number of times you can recharge. 2 days between recharges would give you about 2 years life out of a battery. I recharge it every two days, and charge time is about 2 hours.
Yeh, I have to charge it every day though......... Never lasts longer. I just wondered if you were supposed to do the initial first charge overnight and whether it sets the standard for the length of time you get each day after that?
i guess every hero is different. longest i used my phone without charging is 2 days with moderate use.
before i charge my phone i kill all tasks in the background and clear my browser history. might not make a difference but to me it feels better to have a fresh phone after charge.
Is that with the task killer app, or is there another way?
I can't imagine mine ever lasting 2 days.....

I'm using TaskPanel as a taskiller...
when i got the hero the battery was ~half full. i charged it for about half an hour, but had to stop the charging before it was full.
the battery doesn't last longer than one day, although i play a lot with it (obviously). when i put it to the charger i try to let it charge fully up, and i noticed that the charging is stopped when the battery is full (you see the icon in the not.bar go back to normal green battery, and the phone cools down noticably after charging is completed). concerning this i have no problem to leave it plugged in overnight. checked last night, when NOT plugged in it takes 4% of battery for ~7 hours in airplane mode.

Battery Drain

Hi,
I've been noticing that my Hero has been gulping battery down VERY fast.
In general, the battery lasts 7-8 hrs, which is not acceptable (I'm out for 12+ hrs).
My usage is not heavy. Wifi, Bluetooth and GPS are rarely, if ever, on.
I do read some news and surf the web a little but only for 2-3 of those 7-8 hrs.
Is my battery life normal?
I've been reading people achieving 12+ hours with their stock battery...
2 or 3 hours websurfing is very heavy on the battery, much more so than phone calls. One of the biggest drains is the screen and you having it on for 2 - 3 hours is going to drain the battery I guess
Seems very poor, much poorer than my iDevice that I use more frequently.
Today, after flashing the 2.1 ROM, it has gotten worse.
Battery's down to 40% in 6 hours, and Battery Usage shows 50% phone idle, 50% cell standby.
I've not even touched the phone since unplugging it 6 hours ago ;S
Is it possible I've a defective battery?
If your battery is down to 40% after 6 hours of it being idle (no screen but switched on) then either you have some power hungry app(s) running in the background or the battery is defective.
At the moment my battery is showing 40%. It was last charged about 40 hours ago, and I have had it switched on the whole time with some light use, picking up emails in the background and occassionally switching the screen on.
I ran task killer and sync was off.
One thing I didn't do was charge it for 10-13 hours straight on first charge; I just unplugged it when the led turned green in ~4 hours (impatient...).
Could this have affected battery life?
Nope - when the LED is green it is fully charged. No minimum charge times suggested in the manual.

That is amazing battery life, I never get more than 24 hours with similar use... what ROM and radio are you using Peter? Also, where are you and what network are you on?
I am in UK on Orange, and have standard Orange ROM and Radio - not the latest one but the one they had before 2.73.61.5.
I have read lots of complaints about battery life, but I think mine is fine for a smartphone. I am a relatively light user of a phone - don't do lots of surfing or watching videos. A few phone calls, very few texts, checking emails and listening to some music is all I normally do with it. The other thing I do use it for is I always have the sat nav on while I am driving, but in that case it is plugged into my Brodit mount and charging from the car.
This latest spell may have been helped because I have not been out over those 40 hours - spent the weekend at home, which means that the Hero has been logged into wifi rather than trying to use mobile data. And not used it to make calls or texts or used the music player.
I notice keep Internet connection active take a lot of battery. Go to settings and turn it off and try to see whether the problem exist. It'll will take you a few seconds to re-establish the connecting whenever you need it... not so unbearable considering it'll save a lot of battery.
Same, I notice the mobile chip is using abnormal amounts of battery.
In the morning I watched a 40 minute episode of drama.
Battery dove from 100% to 65%.
To preserve battery life, I turned Airplane mode on.
When I was done with the episode, there was still 55% battery left!
I'm pretty shocked at the battery drain.
I'm using one of the new 2.1 ROMs. They're known for having a bit of a battery-hunger. I solved it by installing the app Ultimatejuice from Market. it's a pay app, but it's worth it. It's also another app called juicedefender (free, less options) that I used before I bought the Ultimate. It also worked good! Now my battery lasts the whole day without any problem

[Q] Battery Concern

Newbie here - I have a stock G Tablet.
Have added many apps and also Flash and it is working great.
My one concern is that however long I charge the unit,
I can't get the battery indicater to go above 93%.
Is anyone else experiencing this ?
hello there,
yes i am having the same problem. no matter how long, mine can't get past the 95% mark. clockwork mod + tnt 2.2
ideas on how to fix this, anyone?
regards
Try to recharge with the device powered off, and let it charge for at least half an hour after the light turns green.
I've left it plugged in a good 2 to 3 hours after the green light came on.
It still only reaches 93%.
Is it a bad battery, bad charger, etc.,
Any thoughts... anyone ?

Do a full cycle, all the way dead and then charge as stated for about 30 minutes after the green light comes on. It could be just a calibration problem. How long is the battery lasting for you?
I use it for short periods throughout a day, so it is difficult to gauge an accurate time.
A rough guess would be approximately 6+ hours.
I always thought it wasn't good to totally drain this type of battery ?

I think this is a LiPo battery - if so, then its is OK to let it drain all the way - just don't do it too often. You should *always* do two full discharge/recharge cycles on any Lithium-based battery as soon as you purchase it, and again about every month or two.
For removable Lithium-based batteries (i.e. *not* for gtab!), if you aren't going to use the battery for, say, more than a week, the best thing to do is to discharge it to about 50% and then put it in the refrigerator. When you are going to start using it again, let it warm to room temperature for at least a few hours to a day (depending on how big it is), *then* put it on the charger. Absolutely do not charge the battery cold as the thermal shock could damage the battery.
The initial discharge/recharge cycles "primes the pump" so that you get the maximum capacity out of the battery (who knows how long the battery has been 'sitting on the shelf'), and the ongoing discharge/recharge cycles keeps the battery at its maximum capacity *and* allows the calibration electronics more accurately track the slow decline of the battery's capacity.
BTW, my gtab's battery lasted on-and-off for almost 2 1/2 days. That was 'sleeping' it at night (*not* turning it off!) and using it on-and-off wifi/surfing/playing AB during the day. I must say, the gtab's battery life is phenomenal!

Thanks. Tried the full discharge and then full charge with the gtab turned off, left for about an hour after the green indicator, but still stuck at 95%. Even deleted the batterystats.bin file. no change. must i do two cycles of full discharge and charge?
I'm having similar issues. I powered off my gtab overnight and let it charge for 8-9 hours and I have not been able to get the battery to say 100%. I'm going to leave it on all day and let it discharge completely and try again tonight.
Drained battery and left it charging overnight and while I was at work (15+ hours) and its still at 95%. I wonder if I should exchange it now.... I'll give it another week....
If you do two full discharge/recharge cycles and the battery is still not showing 100%, then I would take it back. Either it is the battery or the battery calibration electronics that isn't working (my bet would be the battery). Furthermore, since the battery is "not removable", its just not worth keeping it and taking the chance.
If the battery had been removable, then Viewsonic could have just sent you a new battery instead of having a whole gtab come back....
(Note for Viewsonic - this is where removable batteries are superior to non-removable!)

Before you return it check the actual battery life. If it turns out that it's just a calibration issue and if your happy with everything else, perhaps you should keep it.
Read the thread about my battery test...
mine is different... I can charge up to 100%, and keep using it for few hours at night, put it to sleep, then I wake up in the morning and find the battery completely drained... any1 has the similar issues??

You can try going to settings/applications/running services and turn off all non-essential services before putting it to sleep.
Mine doesn't get above 96%, will have to try the suggestions here but overall I'm still very happy with battery life of the 96%...
thanks, i'll definitely try that... but I don't think I have too much installed or services running since I flashed it with the new ROM.
have you guys notice your battery temperature? i got 2 gtab but both operating at different temperature 1 at 23-24 other is around 31?
My battery life seems pretty good even though it doesn't go higher than 95-96%. I saw in another thread to try resetting battery statistics in clockwork recovery to see if that will fix the battery display problems. I'm going to try that next.
I've got the Malata Zpad (SMB-1002-3G) and mine now wont go over 91% (happened on the 3rd day). It used to charge to 100% no problem for the first two days.
I did a recovery (format) when you press the power and volume up button, but that didn't seem to do anything (other than wipe all my settings and put it back to original factory settings of course)
I'm pretty sure the battery is fine, and lasts just as long, but it would be good to be able to reset the battery status.
PS: My Zpad is not rooted or anything. It's pretty much standard (just running Launcher Pro).

Do you have Clockwork installed by chance? If you do you can charge the battery all the way up and then go into clockwork and reset the battery stats.
Might help...

New owner with dumb questiin

Good day people, I have a dumb question and no need to be polite I know its dumb lol I just got an evo lte and I love it so far. But I did some reading up on training batteries and I'm aware that you can't necessarily train a lithium ion battery but I know there things that you can do help the battery last longer etc.
The first day I did my normal routine, drain it all the way charge it all the way. It took a long time for the battery to die which seemed like it was a good thing. I did that twice and I noticed that after a full charge the battery drops to 97% fairly quickly (like withinless than a min or 2) and from the few days I've had it it seems like it may not hold the charge well over time . I wouldn't normally be concerned about this however this is the first phone I've owned without a removable battery, I don't want to regret it 6 months from now because the phone only lasts 5 hours.
So my question is this I am still within the buyers remorse period should I just exchange it for another onevor am I just being too paranoid? Secondly how do you all train your batteries when you first get the phone? What works for you all who own this phone?
Thanks in advance.

First off, congrats on your choice. This phone has a Li-Ion Polymer battery, which is different from the Li-Ion batteries of yore. I am stock rooted and with medium to heavy use I get a day<12+ hours> out of a full charge with no batt training. I have not experienced the rapid discharge you speak of and if you have no apps causing it, you may need to swap it.
I also get a pretty rapid discharge from 100%->98% - takes about 5 minutes to drop that 2 percent. But after that, I am clear sailing for ~15 hours.
Oh so the rapid discharge thing isn't uncommon then? Hmm

I don't know if it's the same as the og evo and the 3d but when it hit 100% try unplugging it then plug it back in for a few. That may give you the true full charge and stop the quick 2% drop

Yea I'm kind of torn on exchanging it. I may just do it. Of course it would be my luck to get a phone with issues if I did.
That's normal. If this is like the OG Evo (and it probably is), the phone will charge to 100%, then let the battery discharge to 95% before charging back to 100% again. This is primarily to protect the battery and prolong its life. So while the phone may claim to be at 100%, it could be as low as 95% when you unplug from the charger. The rapid discharge you're experiencing is really just the phone adjusting to the actual battery level.
Also, there's no need to "train" the battery. I seem to recall that it's generally not healthy to discharge a Li-Po battery to 0%, and can shorten the life of the battery.
The battery percentage drop you guys are seeing is perfectly normal. No need to exchange your phone. As soon as the kernel source is released by HTC, then the great devs here will be able to bless our phones with some SBC goodness and you will not have that problem anymore
You guys don't think I did any noticeable damage by fully discharching it twice do you? I'm going to charge it and see what happens I don't have any immediate thoughts of exchanging it based off of what you guys are saying. I'm going to charge it up and post results. If its not like what you guys are getting life wise I may exchange it as I still have like 5 days left.
Minor update 7 hours 27 minutes 52% left.

No, it's fine.
Fully discharging it just reduces the number of cycles left you have. Most li-ion batteries have 1000 charge cycles. Battery charge is not an exact science. Do not look at it like you are not getting the full charge.
So at the end of the day it looks like roughly 8 to 9 hours of moderate to heavy use on my phone moderate for the first 7 hours heavy for the last 2 and some change. Does that sound about right?

Battery LIfe Drains quickly

has anyone else suffered from this this is the 3rd time this has happend to me in 2 weeks i leave my phone charging overnight then take it off when i go to work so its at 100% charged then the battery has been draining really quickly this happend to me on tuesday and again today on tuesday it was at 20% at 11:30 am i take it off charge at 8:00 am and today the battery is already below 50% and its only been 2 hours since i took it off charge keep in mind i hardly use my phone at work and the days i do use it more than usual i still go honme with a battery level of around 50% when im off work wondering what can be causing this or do i have a faulty battery??
You got something killing your battery way too fast. Take a look at what you have downloaded/installed. Try wiping it clean and install everything back, one at a time to find the problem. I'm using Freeza's ROM and kernel, getting a full day of moderate usage and usually ending up around 50-60% by bedtime.
You in a bad coverage area?
