S III Battery life...

[fireidiot]

Yes it helped, greatly. I have not put all my apps back on, but I am about 60% there.

It does erase your contacts, so sync them with Google and you will get them back. I removed my SD card to make sure nothing got erased. If you have something and it is not on your SD card, you WILL lose it.

After I did the reset, I let the phone go completely dead and then charged it fully.

Then what about all that recent advice about periodically "conditioning" and "reconditioning" your battery by running it down all the way and then recharging it?

Bump. We get so much conflicting advice. Could someone please explain this to me?

You will continue to find conflicting advice floating around regarding "conditioning" and "reconditioning" of batteries. I'll not be surprised if someone jumps in and contradicts me. But if you really go look at technical papers about the battery technologies themselves - the "conditioning" and "memory effect" which the conditioning was meant to address - are pretty much legacy from older battery technology - NiCad, and to a lesser extent (but still there) NiMH batteries. The current generation of Li-Ion batteries exhibit no memory effect, and don't require or benefit from any "conditioning" regimen.

The ONLY reason to consider anything like "conditioning" is to possibly re-calibrate the measuring technology within the phone circuitry itself which measures and displays how much battery capacity you have left. For that, there may be some merit to *occasionally* (not all the time) letting the battery completely discharge to where the phone goes off, and then recharge to 100%.

Thanks. This jibes with my memories of warnings when lithium ion batteries first came out. I thought something might have changed. Thanks again.

Hey thanks a lot, KreepyKen. I kinda was figuring it must be something like that. So that's all it does, huh? Just hang's out, waiting for someone to call, whilst using up the battery. Come to think of it . . . that reminds of some people I know. ;-) Thanks again.

No problem. But keep in mind that the number is a percentage. Just because the percentage is high, it doesn't necessarily mean it's using a lot of battery, just that it's using more battery than other processes. For example, if the phone sits on your desk for 4 hours, the battery is at 92%, and your Cell standby battery percentage is 75%, you need to realize that is 75% of the 8% total train, which equals 6% of your battery life eaten by the cell standby...for four hours, that's very good.

Everything that happens on your phone uses battery charge. If you're using your screen a lot, expect the #1 drain to be the screen. If you're not using your screen much at all, expect the #1 drain to be cell standby. If it's the kernel/Android System that's eating battery, restart your phone.

It's all relative.

I read on this battery site that it's not good for the battery to charge too fast or it can mess it up. I also read its not good to fully deplete the battery then charge it back up. I usually let my battery go to about 1% before I charge it back up to extend the life, I don't fully deplete it

I would suspect, and as DallasFlier suggests, that the phone has a built-in mechanism that won't allow the phone to accept too much juice. I don't know if it's variable/based on battery temperature or if it's a hard-coded limit, but phones must have some kind of self-regulation to keep phones from exploding due to overheating. Most people know nothing about electricity and do all sorts of crazy things because they don't know any better. So if phones didn't have a regulator, people would be setting their houses on fire and melting phones left and right.

How is your cell standby percentage so low?

 

[Trigger73]

Dunno, i use juice defender with the basic setting. Maybe that has something to do with it? I forgot to note that the battery is the 4200.

Oh. That's a pretty important piece of info

 

[carlt828]

Yes it fits under the stock cover. They also have a 3100mAh battery and I know they have a 3200mAh but the 3200mAh comes with an extended battery cover. I'd rather keep this baby as slim as possible...

+3 where did you find it? All I've been able to find are 2100 & 2200 that will fit under the stock cover.

Thanks again, KreepyKen. That's interesting and informative.

Btw, fellow member's, is there somewhat of a consensus that 'Juice Defender' is probably a good idea to run . . no matter how well one might think that their battery is performing?

At first mine was not that great but after a day or 2 of using it draining it fully then charging its great! I did order the spare battery charge kit from Samsung today cause coming from an iPhone I am thrilled I can swap batteries when one dies! Replaceable batteries FTW!

One thing I have noticed is temperature. When the battery heats up, the charge drops really fast. Yesterday I was in a 4G area and took a five minute call, the battery got really hot and I lost 5%. I just have been shutting down the phone and waiting for it to cool off, which really sucks. I've never had this issue with my other phones. I love this phone, but this battery issue is making me think about getting rid of it.

I'm stumped by my battery life in the GS3. Some times it's good and will last me 2 days on one charge, other times it will last 6 hours... with no real difference in usage. I have Battery Dr. Saver (not Juice Defender) installed, which can kill all random processes. I usually flip between WiFi and 4g LTE, and only use them together on rare occasions. Actually I'm almost always on 4g. Not a heavy user at all... maybe 30 min internet per day, 5 min talk is generous, 25 texts through Google Voice, and maybe 5 Facebook notifications.

my other battery draining settings:
- have screen brightness set to about 20%
- no auto syncing any email
- Power saving option is ON
- no motion except for auto rotate screen, no screen Smart Stay, no haptic feedback
- screen timeout at 15 secs
- have never used Bluetooth

I just noticed some advanced Wifi settings that I should switch. I just now turned off the auto connect to hot spot, auto notify of open network, and only keeping Wifi on when plugged in during sleep.

I've also resorted to downgrading my mobile network APN to what I think is 4g H+. It's definitely not LTE. I did experience some battery savings from this, but also some connection problems too.

This battery is crazy. Some nights it will go from 90% to dead in the 7 hours it takes me to sleep. Some times it takes the battery 3.5 hrs to charge from dead to full, but other times only like an hour.

I should also mention that I do have Google Voice running almost all of the time because it's my SMS platform. What am I resorted to now though? Download an app to figure it out? Buy a bigger battery? I did great on my GS2 while almost always running Wifi and 3G at the same time.

I read you should not let your battery drain below 10% and I am pretty sure it was concerning the GS3.

I cycled my battery twice. The second time it took what seemed forever to die. I'm loving the battery life so far.

What do you mean, by 'cycled it"?

 

[winmod21]

Well, I thought I'd try Juice Defender so I downloaded it yesterday . . . [ decided to move post to new thread on Samsung Galaxy S3 Forum ].

Probably fits better there. :-[

 

[yeah yeah]

Using an extended battery.
