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've a feeling it has less to do with the actual widget and more to do with their constant updating when there is a poor or nonexistant connection.

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%
Battery currently shows 51% left

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!
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

Not sure what's happening with my phone, but after removing the plug on my fully charged phone, I will let my phone sit idle for about 10 mins, when I go wake the screen, I see that I've already lost 3% of battery capacity.
The weird part is after this initial 3% is gone, my battery will drain normally. Does this mean I need to calibrate my battery? Is there anyway to do this without damaging it?
It means you need to get a new hobby... seriously, why do you care if it changes nothing what so ever. In order to fix this, you should try not checking your battery percentage every 2 minutes. On the upside, this will probably give you another half hour of battery life as well.(damn a change of attitude would fix like 90% of problems on this site)
On a more serious note, it's likely just because your phone doesn't keep charging when it hits full charge, it stops charging in order to not kill your battery, and lets it drain to like 90% at which point it will charge back up to 100%, so it may be at any point in between when you disconnect it. Even if it is truly at 100% when you disconnect the charger, the measurements may not be completely accurate when approaching 100%, so it is likely, that could make it drop faster at first. You need to do nothing in order to fix this, seriously don't mess with it.

Are you running stock or custom kernel and any custom ROM? Ive noticed this sometimes too but that's because the phone, when unplugged is running services to start phone on battery power versus the cord/wall charger. Check logcats to see what happens when phone unplugged to see what may be happening when phone starts on battery.
I think you are worrying about it a little too much. It could be searching for service (which drains a lot of battery), starting services as someone previously said, heat is horrible for a battery, anything. If the drain is normal after that who knows it could be the ROM you are on, battery percentage not being reported correctly.
Not worth an RMA by any means. Reset battery stats in recovery and see how that works out for you.
Bear in mind, these batteries are cell batteries, a user who plugs their phone in every time the battery hits 50%, is going to notice over a period of time the time it takes to go from 100% to 50% is shorter and shorter, and suddenly, 49%-0 holds a better charge. If you're constantly charging your phone, you'll wear those cells of your battery down. This is where the "hoax" of always letting your battery drain to 0% when you get it to "maximize" battery potential came from.
Hi, Getting close to 2 years on my gs4. The battery doesn't seem to hold the charge like before. How often do we need to replace the battery?

I don't think there is really a set time, its just that when it starts to go just replace it.
I'd usually do it within 18 months so you're on time for a replacement. Batteries don't last too long which is why buying a sealed battery phone is ridiculous imo.
Depends a lot on how you charged it over the years. Some people say it's better to charge those kind of batteries often and don't let them get below 20% or 50%. And If you use your phone while it' charging, that also decreases the life of the battery. High heat or cold also take some time off the battery's life.
Even if you do take good care of the battery, it will inevitably lose it's capacity over the years.

I feel the same way. But maybe nowadays ppl change phones pretty quickly, so by the time the battery's about to die, they're already getting a new one.
I have been using my phone for almost 2 years, and it already loses its charge so i decided to change it. I think it depends on your usage, if you use it for heavy use, it will loses its charge faster.
I bought new original battery after 12months of using old one,with daily usage i can get around 5hours of screen time

Well after 2 years, any good old battery will be singing on the last verse so to speak. Time to change it. Just normal!
My phone is about two years old now and I thought I needed a new battery. Instead I picked up a new samsung charger (the one that ships with the Note 4). I don't know if it's because of the increased voltage output but my phone seems to hold a charge better - and charge faster!

In general, the deeper you discharge the battery, the fewer times the battery will recharge. If you use your phone heavily, and always drain to 0% almost daily, that will result in a battery that will stop holding it's charge very quickly. However, if you don't use your phone heavily, or have access to a charger throughout the day to top up your battery long before it crosses 50%, then it will typically last a lot longer.
The fact that you notice a significant loss in battery performance, most likely means that the battery has either lost significant life, or at least significant enough to how you use your phone.
You may try the "Battery Calibration" app from google play store.
it's free but require root access.
This app remove the batterystats.bin system file. The OS generates a new clean batterystats file soon.
It's like you're refreshing your battery...
Calibration needs to be done after flashing a new ROM, but you can calibrate any time you think your battery is miscalibrated.
I use this app myself and it's great...
hope this help..

Read the last paragraph. Battery calibration apps don't do anything except generate a placebo effect and screw up your battery stats. To maximize battery life, you want to examine what processes are running and kill the ones you don't want to run, using Greenify or Autostarts.
I decided to replace battery after 15 month of intense use.
My S4 had the same problem. I reset the battery stats, and after that it works great now. Battery easily lasts for a full day.
Here's how you do it.
*Let the battery discharge while doing normal routine stuff, until it switches off.
*Turn it on again and use it some more till it switches off again. Repeat, until it wont turn on any longer.
* Remove the battery and hold the power key for 30 secs or so with battery removed(I do it for upto a minute)
* Install the battery and close it up and now connect the charger.
Let the battery charge to 100% WITHOUT turning the phone on.
*After 100% is reached, turn the device on and disconnect the cable and use it as you normally do.
DO NOT RECHARGE in between and let it discharge completely or till the point, it'll just be about to turn off, then connect the charger.

Calibrate your battery. . If you don't have the app .. charge til you get to 100% unplug charger then turn off phone, plug in charger while phone is off. . Charge until it's green. . Unplug and turn your phone on. . Repeat that process 1 more time and it will work
I just bought a new OEM battery from Samsung. What should i do first? Charge it with phone turned off to full then discharge it to 0 and then charge again to max? Do this one time or 3? maybe there is some article about what u should or shouldn't do when u get a brand new battery?
Hello sohail
My s4 has only average battery timing. Which is not enough for me. Plz suggest me some solution.
Hi everyone,
I have a Leagoo T5c with a more-or-less 3,000 mAh non-removable battery, and for the past few month, battery life has been somewhat erratic. The phone would go from, say, 50% to 10% battery in no time, and I would get the low battery warning, but at other times it could hold at around 45% for a while before really going down for good.
Last night around 8pm my time, the phone went completely dead while the battery indicator in the task bar said I still had about 65% left.
I tried what's described here and there as battery calibration: I left the phone turned off, patiently waited a couple hours (yes, yes, that long) for the battery to reach 100%, then left the phone off for another hour before turning it on.
In a matter of minutes doing nothing more than checking my Twitter TL, the battery went from 100% to around 85%, and was still there went I tucked in for the night, leaving the phone in Airplane mode as I always do at night.
This morning, I turned Airplane mode off and the battery said it still had 82%, which means minimal drain during the night, with all radio off.
Just a few minutes ago, the phone went completely dead after the low battery warning, and the battery held less than 10% charge.
WiFi is off, cellular reception is very good where I live, and anyway, I don't see how LTE could kill 70% of the battery charge in less than half an hour, even if reception was spotty, which it's not.
I plugged the phone into the charger it came with, put it in Airplane mode again, and it went from 10% to 70% just now in less than 30 minutes.
I know for a fact that fast charge isn't supported on this phone, at least not with the OEM charger, plus it has micro-USB, so I doubt the charger can feed it that much juice in so little time.
The charger itself seems to work fine: It never gets hot while charging, not the Leagoo, nor my old iPhone 6, since I use it for both devices.
So, long story short, is there a way or tool to ***really*** know what state that battery is in? I've tried both DevCheck and CPU-Z, and both say that the battery is in good health, and still retains its nominal capacity of more or less 3,000 mAh, but I have my doubts about that.
I think the battery capacity is reduced somewhat, and I need to know by how much.
Any help and input would be much appreciated!
I must add that I flashed a stock ROM on this phone (yeah, again...) a few days ago, so maybe it's the ART cache being replenished that's causing my battery issues, but still, the problem is so inconsistant that I don't know anything anymore...
I had to flash the stock ROM again after trying (again...) to root the device (successful, but doesn't bring anything of value) and finding it barely responsive.
I'm gonna leave the phone as is, ROM-wise, but my battery is still a matter of concern, because it dies on me at the 60-65% mark more often than not, though two days ago I let it drop to 30% without the phone shutting down.
Like I said, it comes and goes. I really need to know if that battery still retains its nominal capacity or not. Any help in that regard would be most welcome...
