my last g2x battery lasted like 4 hrs on a full charge what is the best way to charge the new one? do i let the battery run out then charge it?
When you first get a phone, you should let the battery die before charing it. Then charge it completely after it dies, this will maximize your battery life. If you charge it right out the box, you're actually reducing the amount of juice the battery can hold.

That's not really accurate. Lithium Ion batteries have no memory effect like older batteries so charging them from halfway full does not reduce the maximum capacity.
What happens is the phone needs to learn to measure the amount of mAh from the phone and recognize what battery % that means. By taking the phone through the full discharging and charging cycle, the battery drivers pick up on this and will better report the battery level. With a poorly calibrated battery, you do not get less battery, but instead you just will not see accurate information about the charge level. For example, my first discharge went quickly to about 10%, and even quickly below 5%, but stayed on for hours between 5% to eventually shutting off.
The battery still will not die faster, but my phone thought it was much lower than it was, giving it the appearance of dying faster. Point is, you can do the charge/discharge cycle whenever, not just the first time, and it won't effect your long term battery health.
1) do factory reset
2) drain completely
3) charge completely
thanks!
thanks everyone for your advice!
I think it really depends on who you ask. lol Some people will say let it drain first then charge it fully. I have read info on battery maker sites that suggest when you get their battery that you let it charge fully for at least 8 hours, then let it discharge fully. They say to do this the first 5 charges to increase battery life.
When I get a new phone or battery that's what I do. as soon as I get it I charge it up overnight, then let it discharge completely for the first 5 charges. I can only speak by my experience and my experience tells me it makes a difference. Here is my reasoning: me and my ex gf went one day to get new phones. We got the same phone. She started using hers as soon as we left the store. I waited. I charged it up overnight fully and did the conditioning procedure. Our phones were pretty much mirrors of each other app and software wise. Her battery would die out a couple of hours before mine. Battery usage also didnt report any HUGE differences in consumption .
Also every once and a while I go into Clockwork recovery and wipe battery stats(after it's been fully discharged) and re do the conditioning process. It might just be a mental thing, but for me this seems to work
supposedly from htc.....
1) Turn your device ON and Charge the device for 8 hours or more 2) Unplug the device and Turn the phone OFF and charge for 1 hour 3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour Your battery life should almost double, we have tested this on our devices and other agents have seen a major difference as well
I heard/read somewhere that you should never let a lithium ion battery fully discharge. It supposedly shortens its lifespan every time you fully discharge it. Instead, you are suppose to just top it off and not let it remain on the charger, for extended periods of time, once its reached a full charge. YMMV

This is "more" true for everyday normal usage. Yes, you shouldn't constantly fully charge and fully discharge every time you use your phone. But for battery calibration it is necessary/beneficial.
I also hard that during the first charge after turning the phone off you have to strange on your head for ten minutes, then only use your left hand for the rest of the day and you will double your battery life

This is not a guarantee of battery life extension or performance. These are merely steps (in most cases) to possibly help prolong and restore battery longevity.
First lets understand something about battery charging. The most common mistake is to overcharge a battery. While one is inclined to charge when they see the low battery message, overcharging is detrimental to the battery. This is not good for the life expectancy of your cell phone battery, especially if you are expecting longer life from your battery. Over charging heats the battery, and drains its life expectancy.
Second, it would appear that after flashing (ROM’s, Kernel’s etc.) multiple times, your battery might not hold a charge all that well. Trying these steps may help improve battery life.
> Turn the phone on. Plug in the charger (not the USB to computer) and charge completely> Disconnect the charger and turn off the phone> Once completely shut down, plug the charger back into the phone. Let the phone completely charge, while phone is off. In some cases the phone may give a tone when charged. You can check its status by touching the volume up or down> Once again unplug the phone from the charger> These next steps are curcial. 1.Turn the phone on (give it time to boot completely) 2. Power it off again. 3. Connect to the charger once again. 4. Let charge to full one more time. Unplug the phone!
In most cases, this procedure need only be done once. Remember turn off bluetooth, intranet and other applications when not in use. These accessories pu a tremendous drain on a cell phones battery life. This is why they should be turned off, when not in use.

i feel like i do this every time i recharge my battery because every time i charge to 100% then turn it off and plug it in, it takes another 5 min to charge to 100 while its off. Literally, every time i bump charge it.

Mhmm, an explanation of the bump charge. Been written here before, but eh. Maybe someone lost theirs. I lost my txt file with the instructions a while back lol.
The way I see it these instructions only help to provide a more accurate battery count. Whether the battery is displaying correctly or not, juice in the battery is juice in the battery. Nothing more nothing less. This whole battery issue is ridiculous.
I think it'd be a good idea to remove the battery icon from the notification bar all together.

No. Your phone has software in it to detect how much battery life is left for a variety of reasons; it turns more battery-intense functionality off at 5%, the camera for instance, and keeps enough battery power so that it can run its shutdown procedure, instead of just dying and losing whatever's in memory at the time.
You also don't want your phone thinking that 19% battery is 1% and turning off or telling you to charge it, as charging a battery that isn't fully discharged is a great way to lose long-term battery life. Additionally, how much would it suck if your phone software thought that 75% was 100% and stopped charging? You could then be leaving for the day with 3/4 of your battery, thinking it was full.
There are plenty of reasons to want this to be as accurate as possible. Unless you just don't give a crap if your phone is usable or not

I was having all kinds of issues with my battery draining too fast. I unplugged at 7:30AM and by 10:30AM it would be at 60%. I tried the bump charge and all that, but then I realized "It's the apps, stupid!" I started running a task killer after I unplugged it, and now I'm making it to noontime and I'm only down to 80%.

If you are running a custom rom it is also good to delete the battery charge stats when booting back up after step 4. If you have CWM just boot into recovery, go to advanced, then clear battery stats.
There is a way to clear it if you don't have CWM, but I don't remember what it is and I think most people have CWM anyways.
I check my apps frequently. One day my weather widget was going nuts and was using GPS non stop. I pulled my phone out at lunch and the battery was in the yellow. Granted I haven't seen that happen again it has made me reconsider even using apps/ widgets with GPS
widgets kill battery. I had several pages of widgets and I had to wipe by phone, remarkable how much "better" the battery was after that. Weather widgets look great but it costs to run them.

I would love some advice as a noob here. I've only had my Cappy for a little over 2 weeks. I've done the battery calibrate trick, but still don't see very good battery life. I unplugged from the charger at 100% at 10pm last night and left the phone on all night. Wifi and GPS were turned off. Beautiful Widgets is set to update weather every hour. The phone received 7 sms messages during the night. When the alarm went off at 6:30am I was at 70%. It's 10am now, so it's been off the charger for 12 hours. Here is what I show:
Voice Calls 34%
Cell Standby 23%
Phone Idle 16%
Display 15%
Android System 4%
Beautiful Widgets 3%
Android OS 3%
Android Core Apps 2%
antivirus 2%

Would anyone suggest Advanced Task Killer or Juice Defender?
There are some good tips for prolonging and caring for your Battery here: (Can't post links, google search: site:arstechnica.com battery life ask ars)
However, cell phone batteries rarely run over $30 (I have seen capivate batteries as low as $13), if you just always fully charge it you will still see a good 8-12 months out of it, and then just buy a new one. $30 a year is worth it to me to just let the thing fully charge so that I can use it for longer.

If you fully charge and run the battery, done several times, the battery will eventually run better. Surprisingly, there is a "break in" period for the battery.
I appreciate the advice on the task killers and such. I don't use one, and after reading that stuff, I won't. I pulled my phone off the charger yesterday at about 1pm. By the time I played some games, did some web browsing, made some calls and did some texting, it was still at 70% when I went to bed at around 10pm. This morning at 7am, I was shocked to find that it was still at 67%! I don't have a clue what was different. It typically hogs up 25-30% overnight, but this time it only did 3%. I wish I knew what was different. This is so weird!
I go out at night mostly so by the time i leave the house my phones battery is about 75% full. I have the LG G2x. My question is sometimes before i leave i'll see that it's 75% full so i'll charge it back to 100% before i leave. Does charging the phone without it being drained damage the battery? should i just leave it alone next time i go out? sorry if this is already a thread just point me in the right direction.
Thanks.
You're not damaging your battery But if you never drain the battery completely, i'm not sure how good the battery will be after 6 month, so i recommend you drain it completely every couple of weeks.

There are several opinions about keeping battery health for more time. Recharging at 75% is not one of them, but it's not the worth of it.
Here's what i know and what i've heard:
* some manufacturers (laptops) have software that don't allow the battery to charge when it's over 80 to 90% - they say it helps on battery life
* it's common sense that you should recharge when you have 20 - 40% and do a full cycle once in a while (this is what i do)
In my opinion, charging only 25% of the charge in a regular basis will not really help to keep battery life...
I've personally had the best performance from batteries when I let them discharge as much as possible and then charge them to full without interruption.
some have also said that draining the battery too often can also damage it, is this correct?
They like to be ran down then recharged but not all the way down to nothing unless you are having a problem with bat life on a rom

Yes. You should not drain your battery all the time. Use normally, charge it when below 40% and yes, charge it back to full - that's the ideal thing.

+1 that is the best way. Li-on batteries should'n be drained completly because it can shorten their life.
I read somewhere that it is not important when you start charging your battery (20%, 60%...) but it's important that it finishes to charge up to 100% every time
I heard/read that LI-ION batter is good to charge when cap goes bellow 30%.
So my maxx will drain to 1% battery in about 3 days with 3 hours screen time. The thing is once I hit 1% it can stay on 1% and not shut off for hours. Right now its been on 1% for about 7 hours, I have a youtube video going just to see how much longer it will go. Its been playing a youtube video now for about 20 min on 1%.
I just got this phone last week, is this because the system hasn't fully calibrated the battery? Or is the battery defective in some way? Its kind of annoying because you think you are out of battery but it keeps going so I don't really know how much battery I have.
Definitely not normal. I'd do a factory reset to eliminate a software issue and if the issue persists seems like it must be a hardware issue, exchange it
These sound like calibration issues. Can you fully charge your battery and then leave in on the charger for awhile -- like an hour or more? That should calibrate it correctly.
I have never nor will ever let my battery get that low. These batteries don't like to be drained and then fully charged it's not healthy for the battery. I don't let my battery go below 30 to 40 percent if I can help it. Most of the time I let it get to about 50 percent then I charge it.

not to be rude but where is you information or evidence backing your statement? this goes against everything i know and i certainly always allow my battery to fully die then i fully charge it over night while it is off, i believe charging at 40 percent fools the battery into thinking that is the end of the battery's daily life span and therefore dying prematurely due to it believing that 40 percent is the end.
I do not have any real evidence except i've gotten exceptional battery life with my Ultra after allowing a full cycle (draining all the way and then fully charging while powered down)...i have gotten just under 32 hours with 4 hours and some odd minutes screen on with about an hour of voice calls and random other usage such as tapatalk browsing, internet, texting and maybe some email or youtube....i occasionally play some games like the new CoD Strike Force

The best source is battery university. Here are a few good links. In the first, look at the third column (Li-ion), as that's the battery pack in the Maxx/Ultra/Mini

http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
From the second link (emphasis mine):
Similar to a mechanical device that wears out faster with heavy use, so also does the depth of discharge (DoD) determine the cycle count. The shorter the discharge (low DoD), the longer the battery will last. If at all possible, avoid full discharges and charge the battery more often between uses. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles to prolong life, other than to calibrate the fuel gauge on a smart battery once in a while.

Coming from a Gnex, I have a charger within 3 feet of me everywhere I go. I'm trying to break myself of the habit of plugging it in but mine still gets a charge at some point during the day, if only in the car. It has always been my practice to let my phones run down almost to dead maybe once every couple of months. I feel like it keeps the phone's battery meter calibrated although I have nothing to base this on.

What's the consensus on when to charge and how long?
Is it safe to charge the S7 battery overnight, even if only around 50%? Or is it better to wait until your almost dead?
One of the I.T. guys at work was saying you should wait until you're below 20%, then always charge to 100%.
Just charge it whenever you want, this isn't the 90's or 2010. You'll probably replace your phone before you start to see it majorly affecting your battery.
You'll get a very slight improvement in overall battery life if you keep the charge between 25% and 75%. But we're talking very small. But yes, it's perfectly safe to charge your phone over night. The battery / phone / charger electronics won't overcharge the battery.
What you do want to avoid is draining the battery down to zero, or close to it. If at all possible, don't let the charge drop below 20 - 25% on a regular basis.

Thanks for the info. I thought it was beneficial to charge all the way to full?

Lithium Ion batteries are different than older technologies, such as NiCad and NiMH. These batteries suffered from the "memory effect" (although not as badly as most people thought), so it was good to charge those fully. If you always charged them to, say 80%, they would eventually only take an 80% charge. Li batteries don't suffer from a memory effect, so you don't need to worry about that.
The other thing is that Li batteries hate three things: excessive heat, being fully drained, and being overcharged. Tesla stops charging when the battery pack reaches 75% of full charge, and displays that as a full charge. Similarly, they consider a 25% charge as "empty." Then again, a Tesla battery pack costs something like 10,000 bucks, so it's important to as much as possible to maximize the life of the pack.
I still currently own a Samsung galaxy s3, and I have been charging it to full 100% and letting it drain fully until it shuts off. Once i get S8+, should i still be doing this or will that mess up the battery over time. Do you guys drain until 10% , and charge up too 90%? Was curious.
Batteries have so many charge cycles at a certain depth of discharge. My understanding is you get more charge cycles if you discharge less.
So, unlike removable battery phones, I plan on leaving this phone on a charger as much as possible and usingbt the battery when necessary.
The battery change on this device looks hairy!

I See, does the phone stop from overcharging the battery once you reach 100%?
It's best to keep it between 20%-80%
Also, pretty much all lithium ions are nearly impossible to overcharge.
You generally want to keep your batteries between 40-80% I believe is the sweet spot. I will not let my battery go below 30% generally and I top it off whenever available. Forgot where I read it but as others have said your phone has so many charge cycles (500 or so before the battery starts losing a certain compacity). And if you constantly charge from 0-100% each time, you are using a full charge cycle. Instead if you charge it at 50%, you would be using half a cycle, etc.
Someone can correct me if I'm wrong.
