The best ultimate super oober battery trick to make phone last 6 days

I have a question. My battery gets to 4200mV around 80% which means its fully charged.it continues to slowly climb to 100% after that even though it hit a full charge long before it says 100%. I tried battery calibrator but it doesn't seem to help. what should I do?

Use wifiwhen possible. Turn off all unused radios (GPS,wimax,data,wifi)
Also don't run Max brightness when screens on.

If you want a phone to last you six days, u better get a flip phone.
Unless you airplane mode the phone and never use it you will not get more than two days max, which is pointless since its not really a phone in that situation.

I think full charge is based off the mAh not mV.

I dont know how the circuit in the phone works, but when I charge up my lithium batteries for my RC car, while its charging the circuit shows a higher voltage than the battery will actually be at when its pulled from the charger. I also dont know what tells the charger it is full(or getting full) but the charger starts charging at a lower amperage the closer to full the battery becomes.

Yes, your chaging with amps, not volts really.

For the people telling me how to get better battery life there's not what I even asked about in the OP. The guys that said its not the mV and its the mAh that does make good sense. Is there a app or widget to watch it in real time? I have better battery by curve fish that shows mV not mAh. Thanks for the feed back guys!

Grab battery monitor widget and better batter stats. BMW updates every min, but can be set lower. BBS is on of the best apps to show what's using battery.

Thank you so much. I will try them both!
Edit-I installed better battery widget.only problem I'm having is it shows me running an 1500mAh battery. I sent the dev a email which they say to do if its showing an incorrect value. So this should be fixed to. It works great thanks again so much. I now know one more thing about my phone that I didn't before

IIRC The SAMOLED+ pixels are off when displaying black. Google pure black and set it as you wallpaper. That should help.

Also depending on how aggressive your overclock is since it will raise voltages depending on frequencies. Also syncing data is a huge battery drainer. If you kill auto sync and only do manual syncs, it will feel like night and day.

Want great battery life and a stable phone?

Don't use any type of battery monitor, widget or notification.
I was getting good battery life but had a few weird cases of reboots and where the phone would just shutdown and then need battery pull to get back up.
Since I stopped using any type of battery monitor/widget/notification my battery life is much much better (same usage pattern/apps) and I have not had a single reboot or issue.
I just wanted to share this for people having problems. Worth a shot.

I use JuiceDefender Ultimate and my battery life are more efficent!

There are a number of things that affect this. Most importantly, use CPU spy to check how much time your phone spends at each frequency, or rather in deep sleep. Some monitors in certain settings will keep the phone awake, draining battery.

My AndroidOS wake time is much lower after getting rid of the battery status apps

I use Circle Battery Widget https://market.android.com/details?...oid.CircleBatteryWidget&feature=search_result and it has no noticeable effect on battery life.

I'm using Battery Solo Widget (was using Circle Battery Widget before) and it does not have any noticeable impact on battery life. Right now I'm at 36 hours on battery with 24% left

Do you even power on your phone during the day(s)?

Use airplane mode at night while your u sleep. I lose less than 1%

Well the screen was on for 1 hour and 50 minutes (at max brightness) according to battery stats, so I'm not using it THAT much but the point is that a battery widget doesn't seem to have a big impact on battery life.
I also noticed that if I stop constantly closing applications after using them (by swiping on the ICS task switcher), my battery lasts a little longer

and lose 100% of your incoming calls or texts. good for battery life, not good for anybody who has a job/life that requires constant connectivity.

Yeah this isnt an option, I need to see missed calls and what not
However, when I do not have the androidOS wake bug, if my phone is on wifi I lose ~3-7% overnight, which is good IMO

I went to bed last night with 96% and left everything on and syncing and woke up to 88% so I think I'm content with letting it do it's thing. That was my first night with it so I expect it only to get better.

I suppose if you work 24/7 you are correct. For those of us that don't, airplane mode is a great option. Also Google voice solves the missed call problem - you will be notified by email when you take airplane mode off.

As crappy as the battery life is during daily use...idle at night even with wifi left on and updating turned on its still only about 1% loss per hour...Also running the th3ory axiom roms too if that helps.

What if someone calls you and its an emergency? Like one of your kids calling to say they're stranded somewhere? Still a good idea? Or how about just plug in your phone while you sleep? Brilliant!!!

I run the stock GSM battery, it lasts all day so I have no complaints.
If I had the samsung spare battery w/ charger for business trips i'd be set for those flights and airport waits.

App that measures battery?

I just got a battery I ordered two week ago from China that's labeled as 2000 mah. So far it seems to be lasting longer than my stock battery so I would like to see if there's an app I can download that would show the battery's capacity. I know some battery's from China be rip offs but I gave this one a shot and it probably payed off
Edit: Phone been running on battery for 5hrs with two hours on screen time and all my radios on (4g included). Still got 45% to burn.

To measure the battery, I recommend to use 'non battery saver' app.
I use 'Battery monitor widget' and it works great for me.
There are many reports that some battery saver apps are causing more battery drains.

I use battery monitor widget too! However I had to set the capacity of the stock battery n the generic one myself. Is there any app that can just read the capacity on its own without me programming it?

It doesn't look like our phones support the reporting of battery capacity. You would have to buy a meter.

If you are using 'battery monitor widget' too, then click the calibrate and it will ask you couple of things. Before putting any information there, visit the online help pages first and be sure that you are putting the right information.
By doing this, you may get more accurate battery information.
(Sorry, actually I didn't try this by myself before)

I did all that already. I just wanted to test an app that reads the mah on its own soon as you install it. Guess my only choice would be to buy a meter like the other person posted. Anyways I'm getting great battery life so I'm just going to take it and not question it lol. Thanks for the advice tho!

[Q] Battery life

Hello.
I was wondering if my battery life is low or not, so I want to know what your battery life is guyz.
My battery would last like 12hs with wifi always on and facebook, some music here and then and youtube. is it a normal consumption ?

There are so many variables that come into play with battery life that is nearly impossible to quantify what sort of battery life someone should be getting. Screen on time, brightness settings, radios used, reception, usage patterns, apps running in the background....tons of things that will be different from person to person. Also, the actual battery itself comes into play with how well it can hold a charge.
As long as you are happy with your battery situation, all is well. If not, perhaps look into what is using your battery. Better Battery Stats can potentially help you narrow down where things on the software end are draining your battery.

That's about what I use to get.
I went out and bought a spare battery. I'm not a fan of extended batteries so I went with a standard battery for about $10.
I also flashed a new kernel that will help on the screen brightness and underclocking.

Terrible Battery Life

I don't know with the others, but there seems to be mysterious battery drain on my A70. It's night and day, compared to my old ZE553KL with only 500mAH difference in battery.
Is there any tips to get even more battery life from this thing?

Hello,
I have the same problem, battery goes down so fast, very disappointed with battery life.

My battery life is great (6h SoT at least), I usually end the day with more than 50% battery left. Maybe you have some apps draining the battery in the background or the update messed it up so it might be worth doing the reset to factory settings.

Check - background scanning wifi and gps if is ON it drain battery a lot , also if not need change gps accuracy to coarse . Battery draining apps samsung software report itself after 2-3 days .

I actually have very good battery life,i would suggest you to install greenify app and add all the apps in the hibernation list and create a shortcut key on the home screen,one click and all those battery sucking apps will hibernate.

I've never had that application installed

I'm getting excellent battery life.. I'm only using 4g network...

I can't say why but I found out that disabling bixby (voice thingy) makes a huge difference on my A70 with battery.

to those, who use 3rd party battery apps:
I think you should stop using 3rd party battery apps (battery monitoring, saving apps) they consume a lot, too, and do the same as the built in battery app. I experienced when I installed one of these "useful" apps, and it consumed the most battery, so these are fake. Simply uninstall or disable really not used apps. You will see difference in my opinion
