[Q] wifi tethering +battery care - Galaxy S II Q&A, Help & Troubleshooting

hi, so lately ive been using my 3g connection for use with my laptop via wifi tethering. when i have enough battery, i let it drain, and then continue tethering while charging until full, and then drain it again
my question is, with the fast pace of draining and charging almost everyday, will it cause any negative effects on my battery or my phone?

Yes it will just like every battery has a life cycle.
But should you worry.. No as I do exactly the same and have on numerous devices.

oh okay, glad to hear that, thanks!
if you have other methods that would do less damage to the battery in the long run, you can share it here
(maybe leave it plugged in even if full?)

Problem with leaving plugged in is heat as can get damn hot....
I tend to do a battery cycle very week or every flash of ROM/Kernel as the stats get awry since tether takes allot of juice.

Battery drain really faster after using GPS

My phone usually get great battery life, except after using it as GPS.
After done using it as GPS, the battery drain really fast. Within 4 or 5 hours, a near full charge is gone even when the phone is on sleep.
Is this just me or others notice the same thing?

Yup GPS is a battery hog when use, specially if Google maps is running in the background

[DISCUSSION] Our phones' BATTERY LIFE

Hi all, after a lots of pots from a lots of users claiming their battery is great or their battery is ok and even that their battery is a crap... I decided to open this thread to share my opinion with you all and see how many of you think like me.
Here it comes:
For me, BATTERY LIFE is how GOOD-OK-BAD our battery behaves and how much it lasts WHILE USING THE PHONE.
Having looooong periods of deep sleep is just the Stand-By 640hrs that Samsung itself offers with its ACE.
Under heavy use, ACE is supposed to last at least 11hrs using 2g and 6hrs using 3g.
Me just quoting Samsung and GSM ARENA

If you do the math, most of the people that claim to have a HUGE battery life have their phones on DEEP SLEEP (Stand By) MOST OF THE TIME, plus they don't use 3g but WI-FI.
So, when they say: HEY BRO, I unplugged my phone 1 day ago and my battery is still at 30% and then they put a graphic on it you can see that about 20 hours the phone have been deep sleeping. Then you use it and PUFFF!!! A huge percent down...
I don't know if you know what I mean, english is not my first languaje... But what I'm trying to say is...
Battery life is most of the times the same WHEN USING THE PHONE!
Dude stop worrying too much abt battery... Simple battery rule. Charge it when its less than 20%... Let it drain by its own.. Then charge again... There s something called life explore it...
WOW!! What a superb reply... Great, wonderful, splendid...
You're so wise... OMG I can't even believe you took time to reply my request... Thank you Oh Lord!!!
Sigh!
My battery drains so fast on my home wi-fi I tend to browse whilst charging for most of the time (I'm sure it's not recommended). Wish I knew where people get the improved stats for wi-fi over 2g/3g from.
Of course samsung is gonna claim great battery life, they have to sell.
On my experience, i use the phone constantly with 3g for whatsapp and music all the time. I still charge it every night and thats ok. Its a smartphone, a micro computer. Unplugg your lap top and see how long it lasts! If you cannot get a day of battery, youre using your phone too much. The biggest battery hog is your screen, turn it off when not using, lower brightness, dont use 3g and 2g at the same time. Otherwise, get a stupidphone and marvel at your 5 day battery life.

The point about WiFi/3G/2G and battery stats is that if the phone isn't having to work hard to get its connection then it won't drain so much battery. So for example, I have almost no 3G coverage and no WiFi hotspot for miles, urgo if I have them both on the phone will search hard for them and drain battery. I have only 2G allowed and that works for me.
Technically if I had a WI-FI hotspot I should use that because it should provide better coverage than either 2G or 3G, and so the phone won't have to work so hard to get connectivity.
How strong is the signal for your WI-FI, is it very changeable?
I sit about 2m below it and it locks in seconds, varies between 2 and 3 bars on indication. Perceived drain is battery falls from 100% to charge warning in 3 - 4hrs approx.

Data switches off automatically when you are connected to the internet thru wi-fi!
my ace drains battery fastest when i play games,when playing any game 10-15 minutes my battery drains for like 10%
i have good battery life ,,about 36hours when using wifi
the problem of my battery life only happens when the phone is on. I've tried turning it off for a few days and the battery held up too long. So my advice for the battery last long, its always keep the phone off, and use it to shoot on someone's head (devs?). You may even withdraw the battery, lasts longer without recharging.
I suggest that someone makes a rom that doesnt work and keep the phone off, and we will have long battery life

In my case, I've had the best battery life duration with StockRom Lite, AceOne (this seems to fly in my phone).
The AceOne rom seems to "survive" between 16- 18 hours in my chase listening music, checking some emails with 3G (not 16 hours, time by time).
I've installed a rom made by Nathan (TouchWiz) and I was worried about the battery's duration, but since I've installed nims kernel it works better, I'm gonna view how it works

Is it good to charge and use phone at the same time?

My phone has 50% battery left. I plug the cable into my laptop to charge over USB. Then I play some games at the same time. The battery level comes up slowly.
So is it good to do that? Or we should do one at a time: charge or use phone.
I have always done it that way and ive had android ever since it first came out. Nothing should go wrong, at least not for me.

Yeah this is a good question I have always wondered about it... Won't it affect the battery like long term?
Wont harm anything
it doesn't matter if affects to the battery or not, you will trade your phone for another new one before the battery gets damaged
The only issue is that the phone will heat up like crazy so...
If you're overclocked or it's a very hot day, please avoid doing this, otherwise you may damage your phone.

Using while charging overheats the battery and the mobile itself.
Heat is the biggest enemy of batteries (wrt. longetivity), so yes it does reduce battery life. Having said that, most of us upgrade phones in less than 2 years, so it wouldn't be as much of a problem.
But overheating is not good for rest of the phone hardware.

I really doubt that. If the phone or battery were overheating, you wouldn't be able to touch it.
Maybe it reduces battery life, but that can't be much, since the battery gets hot whether it's being charged or not.

If you left it in all the time, yeah, that would.
Using it while charging is fine. Mine charges at about 30-35*C, gaming on top its up to max 41/42. Thats well within limits and its going to have negligible effects on the battery pack.
What charger? Sure it was an dealextreme charger.

[Q] Horrible Battery Life - Second Device- Crap Kernel?

Anyone else experiencing horrible batter drain? Android OS is taking up 50-60% on average and it just eats it up while idle. I'm thinking about a return, this is my second handset, and with a locked bootloader, im losing faith in a quick solution. Any ideas?
Minimal use and quick setup with two to three app dowloads, and my 40% charged new device was down to zero in 2 hours.
I've noticed some battery quirks so far. My percentage drops 3% simply by locking and unlocking my phone within a few minutes. I've also seen it jump up in percentage once so not sure. Maybe there is something in the OS that isn't optimized that's causing the battery drain and quirks? I dunno. Be great to hear from some other people on this issue.

Hi give it a couple of charge cycles it will definitely improve.
Yes, I've got the same problem. The OS takes most of the battery. Idle is fine, but with any use battery drops very fast and gets extremely hot, as well.

Keep in mind that these are new phones with NEW BATTERIES. With that being said, you need to "cycle" (charge to 100% then discharge to 0% <repeat 3-5x's) the battery before we judge and jump into conclusions. Just sayin

For the record, I'm also having pretty lousy battery life. OS taking up 55%+. Last night I charged it to 100%, played with it until it was about 93% and then went to bed. Woke up this morning and it was at 65% with zero deep sleep and 80% OS usage.
Something's funky. I like the phone but can't be dealing with this constantly.
A:
EDIT: Turns out the extreme drain was from the radio. I had switched off LTE in the hidden menu and apparently that causes a ton of wakelocks and prevents deep sleep. As soon as I turned LTE back on, deep sleep came back. So that's somewhat encouraging.
I'll have to look at that. I'm getting a day with light use out of my second phone after a few charges, but it gets a little scary when im using it. I'm staying optimistic, my s3 was just phenomenal with battery life after rom kernel additions.
Can you explain how you turned off/on lte and the menu path?
I dont see an apn option other than the stock one (which im assuming is lte enabled). I'd like to see if it makes a difference. Thanks.
you need to enable network menu in the build.prop and a menu will appear where apn is

This is really disappointing. Physically, this phone is fantastic. It looks great and the specs are terrific but it's crippled by absolutely horrid software which I suspect is the reason for the abysmal battery life.
After my first day with the phone yielded less than 10 hours I decided to do a factory reset and set the phone to Eco Mode. That improved things slightly... I managed to get 14 hours but that was with limited usage. In fact, the only significant difference in results was that, in Eco Mode, Android OS shows that it is consuming 80% of the battery vs 53% the previous day.
There is something seriously wrong with these things... the fact that some people are saying that they aren't seeing the problem has me worried that it may be some sort of hardware-related issue.

I would guess those people that aren't seeing this are not looking at the battery stats, I have never seen Android take up this % of battery on any device and I have been using android since the Hero... about a good 15 devices or more ago I have lost count. Come next Thursday I am going to go switch out for something else if the boot loader is not unlocked yet.

LG V10 Battery Life

How is the battery life on everyone's LG V10 VS990? I've got two batteries, a 3000mAH and a 3800mAH battery, but I find the battery life seems poor on either battery, both only lasting about 6-8 hours, sometimes a bit longer if I'm not using my phone a lot that day. Is this just me or everyone? I know a friend of mine with the T-Mobile variant of the V10 gets almost two days of battery life, but I'm not sure how heavy of a user he is.
A non power user can make a battery last forever on this thing. Weekends, I am not tethering or running Pandora, or getting blown up with group texts, so I can unplug at 8 am, and plug it in at 11pm with 30% or more. Week days, with all those things going on I can just get through the workday from 7:30am to 8pm or so and have to plug it in asap.

See, I unplug at 7:30am and can only get to about 3pm before I need to swap batteries if I'm not careful about how much I use my phone. Though I do a lot with my phone, it doesn't sound like as much as you do. I've checked the battery usage and it always says the Screen and Android System are using the most battery, which seems to be normal on most phones, so I know it's not a particular app. These two batteries are also only about a month old.
Don't know, I got mine at release, I do have two batteries, but only carry one unless I travel out of town. I often click to close all apps often throughout the day and use Wifi whenever possible and whenever not tethering to my iPad.
After root, I get roughly 2 days on a full charge. Greenify and freezing apps has increased battery life dramatically

Verizon location services app eats battery at a crazy rate even when the phone is asleep. Now when phone is sleeping it eats about 1% per hour instead of the nearly 10% it was eating. The stock battery is small to. 2800MaH for a phone this size is not a lot. GPS also eats battery. If you have location on try turning it off. Also if you live on the edge of a cell zone and your phone has to constantly keep talking to the tower it can use a lot of battery. You can test this by putting your phone into airplane mode, if your battery suddenly gets better... then the cell radio is killing you... unfortunately not much you can do for that.
I haven't been using the second battery yet, keeping it around as a replacement because we know what happens after the first year of using them.
