Hi can anyone tell me the correct way I should go about charging the EVO when I first get it? I'm getting it tomorrow and want to break the battery in the right way (if there is a right way), let me know!
I don't see how you should go about it in a special way different than every other phone
It's a LiIon battery as all of them, none basicaly needs to be cycled to work efficiently.
Or was this your own way to broadcast that you're getting the device tomorrow to let the rest of us drool in envy?
I definatly will say that the first few charges of the battery do NOT last long at all, battery drains REALLY fast.
This may be placebo, as I know that Android will get more efficient as the OS "settles down"
I always make sure to let it run until the device shuts off by itself before charging. Then charge to full and repeat. I try to do this 5 times, but it helps that I have a hero I can drain with, then charge and always have a full battery in my Evo.

so completely drain it then charge, drain, charge, etc?
lithium ion batteries do not need conditioned ... and actually prefer to be charged frequently (or so I have read). Just do a google search for lithium ion conditioning and almost every reference says that only the older technologies need it.
It's actually the phone that needs to learn the batteries fully charged to fully drained levels. A couple of full charge-drain cycles teaches the battery meter in the phone. Same deal for notebook computer batteries.

* Not sure if this applies to the battery in the EVO as I have never taken one apart yet ***
From what I recall most notebook (if not all) Lithium * batteries have an integrated charging / safety chip on the battery http://www.sbs-forum.org/ that maintains information about the battery level (via SMbus) and charge information. It is this chip that will report the current battery level and will disallow you to charge a battery at a certain point due to safety concerns.
What is common though is that it takes a couple of cycles for the onboard / outboard battery chip to learn the charge level which the host OS will just blindly read for the most part.
condition your battery
When you have a new cell phone battery there is a residual charge left from manufacturing..it may even say it is fully charged but it is a false reading. You need to charge the battery before you start using it for 8-12 hours. Then, use it down to about 25% and charge for another 8-12 hours. Repeat this process for the first 3-5 charges and then your battery will be conditioned.
After the initial conditioning your battery will last the longest if you do not let it run out until it dies. It is best to charge when at 25%-30% capacity.
Good luck!

Wow. First off, thanks for resurrecting a thread that's over a year old.
Second, your post is completely wrong. Lithium ion batteries do not need to be conditioned at all. Just plug it in, let it charge, and you are good to go.

Really cuz It took a month for my battery to get 36+ he's because I didn't charge it right ( i use sbc) when I got and with my 3d I get 24+ hrs due to battery conditioning. Say what you will my girl does the same with her iPhone and get 2 1/2 days out of it while another friend of mine didn't and her battery is dead after twelve hours... no dis respect dog but it works contrary to beliefs

Use the search please..calibration methods are tried and true..nothing more to see here..let this thread die as the other poster indicated.
Search for battery calibration. I would copy and past the url's for you but I literally found 10+ threads about calibration methods for the EVO within seconds so it will be super easy for you to read one of the methods and apply for what we now see as perfect results.
As far as I know now, nobody complains about EVO battery life anymore unless they are using something to drain the power, bad coded app, kernel or poorly coded ROM etc. It happens sometimes but usually enough information out there to support fixing the issues once you see them.
Hope that helps and good luck..

Some advice I can shed on this is having Wifi on all the time, (by all the time you mean at least 24/7), that could be a strong point why your battery life is low. Another thing is the number of apps that require data being pulled running in the background
1. Having Wifi on for the time you state is bad if you don't have a signal. Reason why is that since there is no signal for your Wifi to obtain it will continue to search and fail, search and fail which actually drains some good amount of battery being forced to repeat such a task unlike when having a steady signal it's usage becomes minimal
2. High number of data pulling apps also works the same except then have the option to change the time they pull data which can be usually found under settings/options tab
Try these out and let us know how it goes =]

Hmmmmm
I barely noticed that you are running a custom rom. After flashing the new rom did you wipe battery stats? If not, that can actually affect battery life as all roms run differently and different data is applied to the battery stat
There are two ways to go about wiping the stats. You can boot into recovery and Wipe Dalvik Cache under the advanced settings or you can download Battery Calibration from the marketplace which in my experience is a lot easier
Battery Calibration
The instructions are inside the app on how to implement the process
I had this rom for a while but when I flashed it, I did not wipe data or anything. I decided to wipe data to give it a try and reflashed it. I charged it completely and calibrated it. I am in the process of running the battery until it dies so I can recharge it to complete the calibration process.

DO NOT drain the battery until it dies!!! Just down to 15-20%, then charge to full, repeat a couple times. Over-discharge is not good for Li ion batteries.
People on here keep recommending it, or saying they do it. Its NOT a good idea, and proliferating this bad advice needs to stop. Draining the battery to dead is bad for the life of the battery. Also over-discharge can possibly render the battery unable to take a charge, requiring you to buy a new battery. It doesn't happen often, but its happened to a few different people on this phone, and other phones as well.

You seem to know a lot so i'm gonna ask ya redpoint. People say there is a built in safety zone so even when the battery is reporting as 0 it really isn't. The batteries do not allow themselves to get below a certain threshold for the reason you are explaining. Is this not true? Lots of people who know nothing of xda or cell phones in general let there phone run the whole way out for whatever reason. I would think that cell/battery manufacturers would take that into consideration.
the reason people used to tell you to drain the battery complete was based on an older battery tech that has what you would call a "memory" it needs to "memorize" it's lowest and highest point in order to calibrate the battery. Li-ions do not need that. They actually keep track of your charge cycles.
suppose it can handle 1000 cycles. on the first day, you used up 75% of your battery and put it on the charger to max. then the next day you use another 75% and do the same thing. at this point what actually happens is that the battery will count this as 1.5 cycles rather than 2 cycles. But redpoint is right.
Do NOT drain the battery completely when it's a Li-ion battery. it's old advice for old tech battery that is legit for that type of battery but not Li-ion batteries.
To calibrate your battery, you just use your phone normally. It will figure out where it is supposed to be as you use and charge it over the course of a few days.
better battery life

It is true that there is a built in 'safety zone' so that the battery does not drain completely to zero.
However, it is also true that this 'safety zone' can and HAS failed for some users (including some who are on these forums)
With the way that Li-Ion batteries work, and 'calibrate', there is no added benefit to draining it completely to zero. If there is no benefit, then the risk is not worth it.

These ideas ran through my mind reading your post:
I. You might want to calibrate your battery. I've run into many instruction how to do this (just google the keywords: Desire Z calibrate battery), but basically the ones that do NOT require you to drain your battery to zero first, came down to this:
0. Turn Fastboot OFF!
1. Power on your Desire then connect to your Charger and Fully charge until the LED changes Green.
2. Disconnect your phone from the charger and then power off.
3. Reconnect your phone to your charger with the power off and wait for the green LED.
4. Disconnect the phone from the charger and power it on.
5. Once the phone has fully booted / ready to use ... power off again.
6. With the power off connect the phone to the charger and wait for the green LED.
7. Disconnect from the Charger then power on and use normally.
Many people seem to have greatly increased their battery life just by following those simple steps. I am currently in the process of trying it myself, but will probably need some hours before I can verify if the overall life has significantly increased.
II. You might want to install an App like "Watchdog lite" for a longterm check if you have any apps or processes, that work as a battery eater in the background.
III. if the above tips should fail, you might want to upgrade your radio and maybe also align the radio library (RIL), to match it best with your radio and ROM. But do a lot of reading and research before actually performing that task, since this is nothing for beginners and might even make things worse. This thread might be a good point to start your research.
hope that helps,

Hey I've read on other forums about these battery calibration apps and whatnot, just want to know if anyone has used them and know if they really do work? The wife and I both have the Dinc2 and i loaded andybonestock on both of our phones.. i use my phone like crazy and she barely uses hers. i put drellis's 21 on and UV 50 and within 15 min off the charger i'm down at most to 98 battery and she's already down to 90. her battery drains rediculously faster than mine and they're both the same exact rom's and kernel specs. Will these app's actually work or is there a real/better way to get hers working better?
Use battery calibration from the market and follow the instructions to a T. Her battery could also be defective. Try the calibration first though.
that's what i'm trying to do. I have it charging right now, at 84% then im going to run it.. just wanted to know if there was any proof it worked or any other option
I left my inc2 get charge to 100% and then use the battery calibration,i notice that my battery goes down from 100% to 97% in just 5second,the battery life is good after goes to 97%,but im not sure why goes down to 97% that fast.

Just a heads up, that is normal, your battery will never stay at 100% it doesn't charge to 100% unless you bump charge it (and that is bad for your actual battery). Having it drop anywhere from 97% to 92% is common, after that you will notice a substantial slowdown in battery drain unless you are heavily using the phone.
I added a picture of my battery life as an example of the length I am getting from the ICS Rom I'm currently using. I have my phone oc'd to 1.4ghz and uv -25 across the board. This screenshot was taken after a day full of phone calls ranging between 3 minutes and 20 minutes, moderate browser usage, moderate facebook usage and lots of texting.
Ya I knew it wouldn't stay at 100 at all but like how mine would be at 97 after 15min and hers at 90.. it just didn't add up.. she rarely used her phone and only had about 6 hours of charge, while my battery with excessive use had enough battery to last me about 16 hours. I reset battery stats and then bump charged her phone. Now its fine

careful on bump charging, it decreases the life of the battery itself everytime you do it.
I personally don't use the apps. I've had the best luck with charging to 100%, power off and charge till green light, unplug and do one more time, boot to recovery, wipe battery, power up and unplug. That's just me though.

Charging to 100% and then powering off and charging again IS bump charging, that is bad for your battery itself, it takes away life on the actual battery everytime you do it. I said this above. You may be getting an extra half hour to an hour out of your batterys life but you are decreasing the amount of times it can actually hold a charge each time you do that, therefore ruining your battery for a tiny bit of extra battery life per charge.

The smoking analogy doesn't really relate, smoking can kill you but doesn't always, bump charging for a fact decreased the longevity of your battery hence shortens the time before it does not hold a charge anymore and you have to buy a new one. I made a factual comment, I did not need a condesending response.

What lord said. I was seeing an issue where the battery would drop 8 percent as soon as I took it off the charger. Then if I rebooted, the battery would drop significantly so it was never reporting the correct battery percentage. Calibrating didn't help.
Ending up going with the Epic 4G touch battery and it's been a lot better. They are going anywhere from 15-25 bucks shipped:

Simple Guidelines for Charging Lithium-based Batteries
A portable device should be turned off while charging. This allows the battery to reach the threshold voltage unhindered and reflects the correct saturation current responsible to terminate the charge. A parasitic load confuses the charger.
http://batteryuniversity.com
Charge at a moderate temperature. Do not charge below freezing.
Lithium-ion does not need to be fully charged; a partial charge is better.
Chargers use different methods for “ready” indication. The light signal may not always indicate a full charge.
Discontinue using charger and/or battery if the battery gets excessively warm.
Before prolonged storage, apply some charge to bring the pack to about half charge.
Over-discharged batteries can be “boosted” to life again. Discard pack if the voltage does not rise to a normal level within a minute while on boost.
Wow! You are like Mr. Battery or something!

I hope you are not using a generic battery. I have seen those things spontaneously short themselves. Whatever you do, don't take your battery apart and attempt to rebuild it yourself. Chances are, you don't know what you are doing. I have seen people attempt to fool around with batteries and get hurt.
Remember, lithium ion batteries are a lot like horses stomachs:
1. Empty them often.
2. Fill them often after emptying.
3. Never leave them alone with a full stomach. (Always leave them alone half full).
4. Use them every day in some way.
5. Never ride them hard outside of MacBeth Castle and then walk them for a mile so you don't get killed by Lady MacBeth's agents. (If you use them very hard for a long time, and then use them sparesely afterwards, don't expect them to be stable...and don't expect not to get murdered outside of your castle).

I can't find any logical reason to explain how this method will work. I'm a chemist student, and I know the technology which used in our battery. as far as I know, charge our battery longer than its full time will decrease our battery life.
btw, it may sounds silly. after some years, we'll found that our battery power decreased. it will drain quicker than usual. if this happen, we may wrap our battery into a plastic bag then put it into freezer for 3-7 days.
I don't think bump charging is such a good idea. Bump charging kills your battery over time. I'll link an article later about it, soon as I find it.

charge more than necessary is a bad idea. if you have good phone, they have overcharge protection circuit that cut charge current. so charge over 100% only waste your time and electric bill. if you have bad phone, that make your battery overcharge, and that's very2 bad. bump charge maybe can fooling protection circuit, but that's make your battery overcharge.
here is my tips, it will double your battery capacities.
- charge your battery until 100%
- unplug your charger, turn off phone if still on
- go to your local store, and buy new battery
- swap your battery and charge your new battery
ok, that's a joke. but it's a good idea if you far from electric for few days. and if you use your phone for years, buy extra battery after 6 month to 1 year after your phone release is a good idea (if you have extra money of course) because it's cheaper (a lot of supply in market).
Here's the article. http://byrong.com/PowerTesting/
It's pretty long so I'll post the important points here.
Interestingly enough, improvements in battery management technology have compounded the average user’s perception of this problem. Older phones were rather inelegant in their charging behavior; usually filling the battery to capacity and then switching to a trickle current to maintain the highest charge possible. This offered the highest usage time in the short-term, but was damaging the battery over the course of ownership. As explained at Battery University, “The time at which the battery stays at [maximum charge] should be as short as possible. Prolonged high voltage promotes corrosion, especially at elevated temperatures.”[1]
This is why many new phones will “lose” up to 10% within a few minutes of coming off the charger. The reality is that the battery was only at 100% capacity for a brief moment, after which the battery management system allowed it to slowly dip down to around 90%. Leaving the phone plugged in overnight does not make a difference: the phone only uses the wall current to maintain a partial charge state.

Bump It. Or Should You?
One technique that has gained popularity in the user community is "bump charging." To bump charge a device, turn it off completely, and plug it into a charger. Wait until the indicator light shows a full charge (on the ADR6300, for example, the charging LED changes from amber to green) but do not yet turn the device back on. Instead, disconnect and immediately reconnect the power cord. The device will now accept more charge before saying it is full. This disconnect/reconnect process can be repeated multiple times, each time squeezing just a little bit more into the battery. Does it work?

The answer, of course, is that bump charging definitely works.
So what does it all mean?
If you absolutely need the highest capacity on a device like this, you will need to bump charge. There are currently people experimenting with "fixes" for this, but I have yet to see one that works. Be warned, however, that repeated bump charging will wear your battery faster and begin to reduce its capacity. If you are a "power user" who will buy a new battery a few months from now anyway, this presumably isn't a concern. If you are an average consumer who uses a device for a few years, I would recommend that you stay away from bump charging. The bottom line is that you don't really "need" to do it unless you are actually depleting your battery to 0% on a regular basis.
If you are someone who can top off your phone on a regular basis, do it. Plug it in when you're at home. Plug it in when you're at your desk. As explained by Battery University, "Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory."[2]
Beyond that, the best advice I can offer is to stop paying such close attention to your battery gauge and to just use your phone. Charge it whenever you can, and then stop obsessing over the exact numbers. If you really need more usage time, buy an extended-capacity battery and use it normally.

Still pretty long, but worth reading.
I don't believe it:''(

charge more than necessary is a bad idea. if you have good phone, they have overcharge protection circuit that cut charge current. so charge over 100% only waste your time and electric bill. if you have bad phone, that make your battery overcharge, and that's very2 bad. bump charge maybe can fooling protection circuit, but that's make your battery overcharge.
here is my tips, it will double your battery capacities.
- charge your battery until 100%
- unplug your charger, turn off phone if still on
- go to your local store, and buy new battery
- swap your battery and charge your new battery

+1 its all just wast our time and decrease the battery life. i think use a tweak script is enough

Agree with u :-\:-\
Ive read through XDA that bump charging increases your battery life but reduces the battery's life span
Welcome back stamatis. Yes, if you read my post in the first page it explains how.
Tapatalked.
From what I read, the LG OG has a "Li-Po" battery. When 'breaking it in" or "conditioning" it, is it best to run it all the way down (to zero or 1%) or is it best to recharge when it's "mostly" depleted (10%, 20% or some other level)?
Recharge when mostly depleted. Lithium ion polymer batteries don't like being totally discharged.
I've run it down with battery conditioner and then trickled charged for 6 hours... Did this three times now getting 22+ hours real world and about. 7.25 hours screen on at 61% brightness.

wats the mv charge for the battery? 4350mv? or more

Thanks. That was my understanding about "modern" batteries, but I wanted to be sure since all of the literature seemed to indicate that this was a different beast, but none of the write ups addressed the matter of properly conditioning it.
Is it detrimental to leave the device charging overnight? (having it connected to the charger for several hours after reaching 100%) And, is there an app recommended for deep cycle / trickle charging?

Good information to know. Thanks.
[OT] Although, "Li-Po" makes me think of liposuction. Can we call it "Lion-Po" instead? :silly: At least "polymer" only has one 'o', or it could be "Lion-Poo."
More seriously.... I think I'm going to have to call it Li-Pol or Li-Poly.

I had the same thought. I called it "Li-Po", because that what it was called, in all of the articles that discuss the battery.

It is called LiPo for short, I have been an RC helicopter enthusiast for a few years now and that's what I fly with. With those batteries it is best to discharge until it is around 30% and recharge, but then again those are helicopters.
I am going to get mine tonight are you saying they can fly like a helicopter? Wow

Hey I got the same phone and don't want to mess up the battery like I did with my old phone -_- Such a nightmare..ended up carrying the usb cord around until I got a second one to leave at work.
For the initial charge (right out of the box), did you run it down completely and then charge? Or charged fully first? I read on other sites that you're supposed to charge 7-8 hours on initial charge regardless of what the phone reads, did you do that?
thanks!
No its not
The battery controller stop charging at 100% and switching power source from battery to AC
how do i fix?
My battery keeps skipping percentages :/ this is a new phone too
