My Battery Life WOW! *Pic for Proof*

Using Myn's ROM with the Battery Tweak, I have FaceBook syncing and I have 2 gmail accounts syncing along with Weather every 3 hours, Facebook every 2 hours.
Nothing else as of now and using Itching Thumb App.

Not needed. From the pic he attached it's obvious the phone was in standby most of the time.

Man, you even use ya phone?
What is with this obsession of battery life goin on 'round here? I say, as long as you can get better battery life than a stock rom, you've won. Keeping the phone on for a day or two without charging seems like a good idea, but everyday isn't the same, and one day you may need to use it way more than any other day..if you start that day off with only 30% just because you wanted to see how long your battery would last, then you really gotta limit how often you use your phone just so that it can make it till the next time your around a charger.

How do u check wake time?

I agree, but it want a heavy day. When I finally did have 14% left and used tv flash battery seasoned super fast. I forgot, I'm using juice defender too

The battery needs to be charged? I bought my phone back in June. The battery is now at 70%. I figured I just had to buy a new one when this one runs out.

Barely used phone. Come on.

Display 4%? Is that possible?

I can go a full day and a half, 36 hours, without a charge and I am using the original sense android... and I use my phone normally, I text, read usatoday, tmz, check email a few times, use the xda app... and I have wifi on all the time! What's this beef with battery life on these forums? Mine lasts forever! I just have things update manually, I don't let anything run without my permission.
I do, however, turn my phone off the 6 hours I am sleeping.

wifi is on = low battery usage, atleast in my experience.

Indeed. I got 1 day and 19 hours on stock nonrooted 2.2 back. and i used it for some medium texting. and some gps applications...maybe 2-3 hours max awake time. i dont think you used it much...the excessive 3G usage from FB doesnt mean anything.

You should be able to get what you're looking for from the Spare Parts app.

According to my calculation thats is 69min of display usage.

According to mine, it's 122 min of screen on usage.
I had this scenario on my phone running myn's rls2 + king cfs #11 yesterday:
since unplugged - 24 hours
display on - 1 hour 25 minutes
charge remaining - 50%.

so i wanted to find out how long the battery would last on standby, and to my surprise.. it turned out to be nearly 58 hrs!!! that was on stock sense rom. non-rooted. and of course with very very minimal use. i basically just left the phone alone on my desk or in my pocket all day.
here is the screenshot i took back in july:
but that kind of battery life is unrealistic with normal usage. I am a moderate user (on the higher side), and i typically put my evo on charge everyday in the morning when i get to work (on weekdays). so, the charge on my phone lasts about 25 hrs with normal usage, that usually means about 4-5hrs of Awake Time. this is after rooting the phone. and i am using a stock rooted sense rom. i have had similar results before rooting the phone as well.
on weekends, i find myself charging the phone about 3 times (over 2 days), as the usage of the phone goes very very high.
i have a charger on my desk at work for the weekday charging, and a charger in my car for the weekends.
i have recently installed setCPU, and havent really seen that making too much of a difference, but that perhaps has to do with my usage pattern.
as pointed out in many a threads, signal strength is one major factor when it comes to battery drain. i live in Atlanta and i have great Sprint coverage where I am located, and that makes a world of difference.

it would help if you indicate the battery life that you were getting on stock or any other rom you were using prior to this. because there are so many variables that come into play as far as battery life is concerned. so that will help put your claim into some perspective

hahah.. funny

i think i have an ideea with our battery

our sgs think our battery its empty at 3,7v or 3,68.
if we could change the limit for the battery is considered empty, somewhere in the 3.1 to 3 V, thinking how much could keep a battery, the phone started.
if the battery is not empty exaggerated, I believe it can be used without problems.
Sony Ericsson uses batteries to 3.2 somewhere if I remember well.
I dont know how I could do something like that, that's why I posted here this idea.
from here http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
"Power loss through Protection Circuit
Besides common aging, a Li-ion battery can also fail because of undercharge. This occurs if a Li-ion pack is stored in a discharged condition. Self-discharge gradually lowers the voltage of the already discharged battery and the protection circuit cuts off between 2.20 and 2.90V/cell. Some chargers and battery analyzers (including those from Cadex) provide a wake-up feature, or “boost,” to re-energize and recharge these seemingly dead Li-ion batteries."

If v can do the cut off to 3.5v we.will gain roughly 35% more life. But ib think it will take 5hrs for a full change

Its a lipo battery that is the saftey cutoff point...same as RC cars...going to low will kill your battery...
Sent from my GT-I9000 using XDA Premium App

not too low
not to low, low enoug to have long battery life.
for charge dont matter 2,5 ore to 4. i dont think wil be 5

good idea....do it°!

I'm ready to test it, but how we can change limitation of battery ?
Explain your idea.

Yes, could you explain more ? Do you know how to do it ?

I have few ideas on battery issue too:

Great idea but a moot one at the same time I'm afraid. No one knows more abt batteries than Koreans. They live for them. If this limit could have been set lower it would be lower. Also I have never heard of battery firmware being flashable through a phone.

sony ericsson use this trick to have longer battery life, anyway we dont use a battery 2 years.
i dont now how to implement this trick.

I have the battery monitor app and in stock XXJVK, at 01% the battery is between 3.4 and 3.5 volts.
Fully charged is 4.18 volts or thereabouts but this falls fairly quickly to 4.0 volts which is where the battery stats need to be accurate to show true percentage and not just jump down to 80%.
Fully charged for me takes about 3 hours but I charge all my batteries (three using a separate charger and not in the phone itself.

It's not linear. It falls rapidly at lower voltage. You would gain about 5% I think...

next time
i have a multimeter, next time i verify de power of my battery.(i am surre it not 3.4-3.5v)

Not impressed with 60 Dollar seido "extended" battery..

I sure hope this fairs better in the next week or two. I hardly used the phone, streamed about 30 mins of slacker.com and didn't make more than 10 phone calls and 2 texts.

If it was only one of the 1750mah batterys then you really should've done a bit more research, 3rd party batteries typically only have ~80% of the capacity they are rated at giving you ~1400mah or quite a bit less than the stock battery.

it was a 3300 mah battery

I've never had any issue with battery life with my epic. I charge it every ngiht and it's good to go.

I like my Seidio 3300 mah battery a lot. It allows me to stream for several hours along with my normal usage (a call, couple of txt, beluga, facebook, & tapatalk). Did you let it sit fully charged for a few additional hours on the initial charge?

Its gingerbread, not the battery.

No it absolutely doesn't.
The 20 dollar one on ebay constantly goes to "low battery" dies and then when you reboot the phone it has 40+ % battery left. That thing is junk!

Not the one I got. From a US seller with extra data cable and extended back was like $23 and it does double what the stock battery does. Got 1 for each of my 2 phones. I can get you the link if you want.

What are you talking about? I bought mine for like 14 dollars and its been rock solid for months without a single one of those things ever happening. I also started a thread in the accessory section which has been there for months and not one person has posted issues like that.

You probably should have went with the $20 Yoo Bao 2800mah. I get over 24 hours with 3g on all day and more usage than you.

Got my 3500 battery for about 10 bucks. Lasted about 17 hours with 40% left before I charged it on monday.

I get well over 24 hours with my Seidio 3300, without turning off Wifi, or doing any special techniques to save battery.
Give it a chance. If I remember right, first charge kinda sucks, but 2nd and third improve a lot.

The 2.3 leak is HORRIBLE on battery life. There are complaints of CPU usage constantly, plus we don't know what processes can be killed yet.

Good, back to 2.2 I go

Fyi I'm on acs rom 2.2 and the seido isn't impressive. It absolutely wouldn't last a full day with 4g on much less just 3g with pandora etc. I did all the charging etc etc. Only reason I sprang for the seido is bc sprint paid for it. Maybe I would of done the yao bao batt but honestly I don't think it matters. I have set cpu to 200-800 and never with this phone has the battery been amazing with any rom or any kernal. Just the nature of the beast.

BIG battery problem

Hy everyone,
after i change rom to cyanogenmod7 my battery life is very bad. Here is what i did...
Rooted, installed CM7, battery was bad, restarted battery stats (i red it somwhere on this forum that whan changing rom battery stats have to be restarted), before that restart battery was, well not good as in stock froyo, but average... after that it is terrible. In just 6 and half houers when i was sleeping it was drained 33%, and after i wake up and use phone, in just 15min it loose 10%. When i looke at 'what use my batteru' cell standby is 45%!! Thats not normal, right? How to fix this isue?

have you try to reset the battery stat?

It looks like you reset battery stats when you weren't on full battery.
Only reset when calibrating battery, and your battery is full.
Sent from my SPH-D700

It was full, than disconected from charger, than restarted battery stats, after that drained completly and charged to 100%.

Might have had a bad flash then, unless your battery is still setting in, give it a few cycles and it should start to give you better battery life

And don't keep the minimum cpu frequency value to high. Because the phone doesnt need a huge frequency in standby mode. That also matters.

I also recalibrated the battery and reverted back to stock froyo rom (with overclock kernel and I removed a bunch of system apps). Battery seems to last a lot longer now

Another solution would be a 3000mAh battery i saw somewhere.. phone gets a little bit thicker, but its perhaps worth it?

I will try that. What kernel did u use for that? And how did u remove system apps?
But must say, 23h 18m since of the charger and battery is 41% with some wifi/data, 12-30 sms and few cals. Still not good as FroYo, but not so bad as before recalibration.

For the first few runs after new ROM and batstatts try to have some full cycles

infinity mc4 kernel. you can remove system apps with Titanium backup (button backup/restore -> select app -> un-install). Look out that u don't remove apps that are active used by the ROM. I have deleted like 30 apps + widgets.
yesterday same time, like in my post above, from 99% to 97% with wifi/data on. So much better!!

I have the same battery draining problem since I flashed WildPuzzleRom and I think of going back to stock ROM...

Over the last month or so ive tried various roms nightly's etc and the most i got out of the battery was around 15 hours with the batt stats fix, froyo on the other hand different almost 36 hours at the best and worst still around 18.

Just found my old one dead
