Deleting batterystats is useless!

Most of the time you read responses about sucking battery life after flashing a rom or kernel. Battery life seems to drop dramaticly.
There are a lot of discussions about callibration methods, and believe me, I tried them all. But I got suspicious when I found no differences in the results. The thing I did discover was that after a couple of days the battery usage will become more stable. No matter what callibration method is used.
The only thing that seems to work is to charge your battery to full, after a flash. nothing more.

I had battery life issues that wouldn't go away, so I just installed that some battery life app. Somehow that helped so much

Seidio is coming with a 5000mAh battery. Problems solved.

I believe the purpose of deleting battery stats is to calibrate the reading of the battery gauge in the note, nothing to do with battery life!

+1 Doing a reboot then a full charge with display off always chills any battery overheating I've had.
Deleting stats will improve calibration so that the Note doesn't discharge for two hours and show 100% , then discharge another two hours and drop to 80%. Instead calibrating will show 90% after two hours then 80% after another two. The net result of battery use is still the same, only the metering is a little more accurate.

With regards to calibration, the Galaxy Note has the same MAX17042 fuel-gauge chip as in the Galaxy S2.
Entropy512 posted about how this chip functions on the Galaxy S2, and how different it is to the HTC devices which have a different way of measuring charge that does need calibrating now and then.
From what I understand, although the MAX17042 chip can 'glitch' readings sometimes, it tends to 'self-calibrate' over time:

[Q] Battery issues with my phone

Hello there.
My phone has a bit of a problem with battery drains.
I have a MB525 with CM10, 17/02 build.
The issue:
It's about the frickin battery drops. It drains too fast and then it drops from 80 percent to a whalloping 50 percent, and then from 48 percent to 15 percent. And then to 4 percent. Not to mention the phone's temperature rises ridiculously when I use 3G.
I have already tried:
- undervolting the battery (no significative results)
- letting it drain completely and then charging again (did not work, battery still drains)
- clearing battery stats (no effect)
While charging, the battery jumps from 50% to 100% fully charged.
I am seriously considering buying a new battery, but I'm afraid it's an issue with the ROM rather than the battery itself.
Any other ideas are welcome. I need to solve this issue ASAP.
Thanks in advance.

Yeah, I was almost certain of that but I was reluctant to buy a new battery and face the same issue.
Just like you, replacing the battery solved the issue. But I still experience battery drains. Must say it's A LOT better now though.
Any tips on tweaking my software to consume less energy (vsel, etc etc) are appreciated.
Thanks!

i've got the same problem with drops/jumps when both discharging and charging....... bought a new battery and still have the same problem so not sure what it is. I bought it from what seemed like a reputable amazon marketplace dealer, so hope it wasnt fake

if my battery has any probs then it'll not charge upto peak i've chk the Vltg levels too...
I dont think so that battery has any probs coz before calibration on that particular ROM I was getting exact flow from 100% to 0%.....so after that calibration m getting that drops so Do I make a clean install or remove the battery profile.....how to remove that battery profile n make a new one?...

Ok, instead of reading around to fix your problem you made a new thread about the same thing.

There is a thread "battery drops explained", just a little down this very page that explains it all. If your battery is >1,5 old, it's getting worn.
Li-Io batterys have a lifetime (end of life is when it only has 80% of it's capacity left) of 500-700 charges. Nowadays people charge their phones at least every two days. Do the math. You'll see some more batterydrops at 20% and 70% (I think), the sum of these drops is how much juice your battery has lost permanently.

Post your battery life here!

I've been noticing and reading many many posts regarding how bad or optimized our battery life is.
I had this phone little more than 24 hours now. And I feel like it hasn't fully when through the battery cycle. Thus killing my phone in less than 10 hours. This is with very light usage as well!
I've also turned off gps and wifi.
I have turned on stamina, along with various other battery saving features.
Now I am coming from galaxy s3, note 2, and iPhone 5. (my iPhone has this same issue and cleared when I've started using the phone and going through few charging cycles)
I just wanna make sure that our phone isn't plagued by the software, hence this phone is only available via t-mobile or Sony (unlocked as well).
Please post your battery life photos.
Including rooted or not.
Also post which rom / kernel you are using.
Mine: stock from t-mobile. And not rooted.

We already had/have a similar topic in the Q&A section, no need to open a new one.

I see a lot of wake events. Check what's keeping your phone from deepsleeping with wakelock detector.

Yup you have a lot of wake events, I had this problem too. I reseted, reflashed firmware multiple times and still experienced problems until I sent it to Sony and somehow now there is barely any awake entries at all. Only screen entries appear (blue line on screen) and no lines on awake.. I do still get *backup* wakelocks and some qcom_RX_wake lock though

i get about 20+ hours of stand by and around 3-4 hours of screen using it normaly not playing games

The phone was horrible initially and on 4.1.2 then after the 4.2.2 update it has been brilliant. It lasts me just over 24hrs on normal us with screen time between 5-6hrs. I'm very pleased as by 17h00 it is normally at around 55%. So it lasts me a full active day.

After 4 months my Xperia Z barely lasts a day with just 1,5h of screen on time. Sony said the battery is good. Restored different firmware, tried 4.1, 4.2, CM - nothing helps. I'm very unhappy...

The media server keep draining my battery...
But when I switch my sd card to a empty one or just remove it the media server nolonger drain my battery.
So I only keep a small amont of pic and musics in my sdcard and that makes the battery can last more the one day

the battery life was improved from 4.1 to 4.2 . That being said, the battery life is still much to be desired.

Tbh I was really worried about the battery life on the Z, I have had my phone nearly 24hours and I am not concerned by bad battery life so far. The battery seems very good actually, its no S4 but the S4 does have a bigger battery and uses a AMOLED screen. Iirc LCD/TFT use more battery or maybe I have got that wrong.

I'll assume you are not a heavy user of some sorts? The frequency of usage i mean.
I'm not sure about the screen part though but it does make sense if AMOLEDs screen uses less battery than LCD/TFT screens since they actually off the black pixels.

You should let your phone die at least once a month, then charge it all the way to 100%
With the phone turned off. I promise you will get the best life out of your battery. Good Luck MF.

No.... Just, no.

Same problem
I had the same problem, I think I have to buy a new battery

A couple of things...
When applying an update on Android platforms, the battery stats are usually wiped, this results in wonky battery drain and charging indications and it usually lasts a few days to as long as a week.
So, the short story is, see if it doesnt correct itself after a week.
On occasion, Android updates dont quite go right and regardless of how Google 'intends' for updates to go, 25% of the time, youll end up doing a factory reset after a firmware update (poor performance, new error messages, wonky power issues including higher than normal battery drain and slow charge rates).
Again, the short story is, after a week, if it hasnt corrected itself, Id suggest a factory reset, then give it another week to see if the battery issue corrects itself. Obviously, realize that if during that week you install anything new that this could affect your battery life. I personally try to keep my phone as stock as possible and disable as many stock apps that I know Ill never use (my Note 3 is at around 25 stock apps disabled and Ive only installed 15 of my own apps, none of which would likely have a negative impact on battery).
Best practices for the proper care and feeding of Lithium Ion batteries is pretty straight forward. There are alot of myths out there from Nickle Cadmium batteries that just dont hold true for our current generation of batteries.
1. Whenever possible, keep the battery charged. If you have an outlet available, plug your phone in, regardless of whether its fully charged or not.
2. Try to keep your battery / device in typical room temp environments (ie a temp range of 60-85 degrees F). Obviously, this isnt always possible but dont intentionally leave a battery / device sitting on the dash in your car in direct sunlight (direct sunlight can raise the temp by as much as 25 degrees higher than the actual ambient temp), dont put your battery / device on top of a heater, etc.
3. Drain the battery periodically (referred to as a full discharge*), currently, the rule of thumb is once every 3 months and re-charge with the phone OFF, once the phone has a 100% charge (use the volume rocker to see the current charge without having to boot the phone), unplug the charger, THEN boot the phone. This gives Android a chance to see what a full discharge and charge should be (and cycles the battery giving the electronics inside the battery a chance to see the same discharge / charge).
* Note that a full discharge in todays components is when a device shuts itself down when on battery power due to lack of power in the battery to continue operating said component without damaging the battery or the component any further. Do NOT continue to turn the device on after it shuts down in this manner without first plugging external power into the device as this will likely dramatically shorten the life of the battery.
The last rule is most important..
4. IMPORTANT! Use your device like you normally would. The above three are tips for making a battery last as long as possible but when and if your phone makes you change how you live your life to any degree of extremes, you've forgotten the point of what your phone is.
And I will now give you source information to the above, these guys are the battery experts...
