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...

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)

I think all it does is refresh the battery checker, doesn't really affect the battery.
I did this and it lasted just as long if shorter than if you don't do it.

Im on my second Epic. Both have had problems reading the correct battery life.

well it works great for me... i kno the batt stats dont show right but if it thinks its gonna die it will no matter what charge is left, maby all this does is put the right charge% back on the screen...idk... but its a noticeable diff on life for me... especially after flashing something in cwm

I had that issue with my epic; I used this thread:
Calibrate Battery thread - This is how you do it!
http://forum.xda-developers.com/showthread.php?t=884684
I used the powered off method; my phone would display the blue indicator like it was full but the percentage would say 97%, that thread fixed that for me.

Ya I know bout that already, & I've did that a long time ago lol my phone was unplugged @ 9am its now 545 & I'm @ 77% & when its about to die I will do this lil trick & bam 10% turns into 30% or more...

So I'm @ 4% 12hrs unplugged been listening to pandora about 5hrs constantly checking xda all day txtn my ass off & im bout to do my trick... Reporting back in a min
I'm back with 18% not the best but that's how ot works...
Sent from the Trans-Epic Express

Here's another way,
With your phone turned on plug it into a charger. Wait until the blue light turns on. It may read 97%, if so, wait another 15 minutes.
Once the charge reaches about 97%, the blue light turns on and the charge current switches to slow charge. It will charge to 100%, and then cycle between about 96% and 100%.
So, follow the OPs instructions or do nothing.

You,know.... That's one thing that hor (htc) got right. All htc phones charge at a rate of 1% per 1 minute. On our epics, its about 1% per hour. Hor.

Then wonder why you ever wasted time plugging in your phone. Best accessory I ever got for my epic. The wall charger increased the battery life on the stock battery as well.

Looks like your screen ate a big chunk of that. Maybe you had an application running that disabled dimming/auto lock? Or maybe you have autolock disabled?

No, it was valid screen usage. But I normally pull between 3-4 hours of screen on --- this is 30 minutes and the phone is dead. xD

No one else will have a clue as to what happened either unless you give more information than that screenshot .
ROM? Min/Max frequencies? Governor? Did the phone feel extremely hot during those 38 minutes? Did you try a reboot? What happened after you recharged it? Same or better battery life?
I didn't even know it was possible to eat through the entire battery in under an hour. Seems like it might be a messed up battery and/or battery calibration thing. If you want more information than in that screenshot, you can try installing BetterBatteryStats

I'm thinking it was just a fluke... I woke up, did some browsing, ran a timer (hence the screen-on time), got in the car to go to work and "14% remaining" popped up. I rebooted a few times to see if it was just reporting incorrectly --- but it had actually drained.
Typically I pull ~13 hours, ~3 of screen-on, and ~7 of Pandora. I'm more than satisfied with battery.... normally. It seems to have gone back to around that level after a recharge, but I'll know for sure tomorrow.

Battery was fine today. Sitting at 23 hours on ~130% battery (some slight charging halfway through), 20% remaining, 3.5 hours of screen, and 7 hours of Pandora.
I guess my phone had a case of the Mondays.... on a Tuesday.

Most likely had something go wrong with the battery stats.
I had it happen before. I knew my device was around 30 percent battery life. I hooked up to the charger and in less than 5 minutes it said 100 percent. So it would charge further.
Drained the battery fully and quickly of course like the op and fully charged. Haven't had it happen again though.

The battery reporting on the nexus is pretty bad

Is my charger not working 100%efficient?

I have N9005 MJ7 rooted
iam using galaxy charging current pro, to measure my charger output, but with my phone gives only 1200mah, while our charger should gives 2000mah, iam using the original charger and cable which came with the mobile
is it normal, does anyone got a better score? which apps do u use?

That app is OK and probably your charger is also OK - the circuit that controls charging is probably limiting the current in order to keep it safe (for instance if it is too warm it might use an even lover current). Also the current is optimized as to be different at different levels of the battery capacity.
That being said I am always charging over night with a safe USB port - that way the current is 500mA max and the battery life is maximized, while I still get a completely full battery in the morning.

Yes, but:
- the S4 does not have the same charging algorithm as the Note3
- he was probably charging the S4 (which has different battery, charger and algorithm) at 1000 mAh or so (which was the most important point I was making, the 500 mAh are not 2x safer, are probably 4 to 8x safer, probably 20x safer than 2000mAh, that is not a linear thing)
- I think the S4 batteries had a certain defective batch (the media spoke at some point about it)
- there will always be a certain very small percentage of batteries that WILL go bad "no matter what", but that is usually exceedingly small if the charge process is done correctly.

Streamed music to my car while driving for a while
browsed reddit/xda and other forums a lot... mainly on WiFi.
Had data/wifi disabled when I didn't need it on... really no point. Takes 3 second to enable it again

LOL Oh. Yeah your right. Didn't realize that. I have wireless chargers everywhere "even made one that was non-slip for my truck" must have put it on one sometime and forgot. Sorry bout that guys. Didn't mean to post a false reading LOL But still I've seen pretty close to those numbers several times without charging.. Depends on what I've been doing of course.
Btw That was an old screenshot I just had in my gallery from not long after I got the phone.

Ive gotten 34 hours out of it so far im really impressed

I have the moto Maxx, Mexican firmware. I´m from Argentina.
Could you tell me guys the version and the baseband of yours?
Because it seems that the latin america version the battery is barely poor.
Thanks!

Damn... Going beast mode with this battery. Would've gone longer, but gotta use it more tomorrow when I'm out. Ya, I know I only have 4hrs of SOT. Haven't been using much

I assume anyone getting more than 48 hours of battery life is turning off data, or at least disabling updates/background data. Just out of curiosity, do you always keep that turned off, or do you just do that when you're seeing how much you can squeeze out of the battery? In my mind, the big reason to get a device with a big battery is so you don't have to baby the battery like that.

I disable data and auto sync. I've done this for every phone I've ever owned. Not to preserve battery life, but I have no need to have it on 24/7. I turn it on when I need it.
