Another battery drain thread....
The battery life on my UK S2 during the day is fine - from 8am to 5pm in the office it goes from 100% to 75%, with 3G on the whole time (no wifi, GPS or bluetooth). I check emails throughout the day but make/receive very few calls.
Last night I charged the phone to 100% then installed ZDBox, put the phone into Do Not Disturb/Airplane mode between midnight and 9am using ZDBox, and left the phone by my bedside upstairs. When I checked it at 08:50 this morning the phone was still in airplane mode but the battery had dropped to 25%.
If I can go 9 hours in the office with 3G switched on, and occasional email checking, and still retain 75% charge, why would it have dropped from 100% to 25% while in airplane mode for 9 hours at home overnight?
The battery usage stats at 08:50 this morning showed:
Android O/S 96%
Android System 2%
Dialer 2%
I'm running stock XWKI4 (2.3.4), upgraded via Kies and rooted.

Search XDA for BettertBatteryStats download.
Install and after 24 hours check for wakelocks and see if a rogue app is draining the battery.
Edit: here it is.

i would also urge people to purchase this app in the market to support the developer who is always on hand to offer assistance on XDA and always posts updates on here too, it's well worth the small charge for a great app.
now that ours is years old,. i get maybe 6 hours tops on a full charge.
what can we do to get more life? remove and replace?
please post links below, thanks.
Mine is almost 2 years old (bought April 2011), and with just surfing and light video watching, I get 8-9 hrs on a full charge. Li-Poly batteries like ours are not supposed to be sensitive to differing battery-charge patterns, but, I generally let the charge drop to 1% before I recharge the battery again.
From last 3 days battery drain of my Micromax Canvas HD A116 has been tremendous especially at night in standby mode. Before I go to sleep at around 12:30 a.m When I check the battery it's between 40% - 50% and when I get up at 7 a.m in the morning just to find the cell has got switched off. The drain is so heavy that it doesn't even power up for the alarm. In the attached pic you can see the complete drain marked in red color and the cell standby and phone idle are the highest battery consumer.
Previously I thought it was BBM messenger which is the battery consumer so I removed it but in vain as the problem still continues. Kindly help as what I need to do to resolve this problem.
Device: Micromax Canvas HD A116
ROM: JB 4.2.1

Download and install Juice Defender from Playstore. It won't drain your battery again at night.

Well I really don't think the drain is due to application as if you see in my previous screenshot I am charging the handset and by 12:30 in afternoon I charged it completely to 100%. That charge last for almost 12 and 1/2 hour without any recharge as you can see in the current screen shot attached even after 11 hours battery was at 47% and then some what near 35% it made a steep drop to 15%(strange) and then it lasted for like an hour or so. Beside that my data connection was continuously on and all sync was on. My talktime was of 4 hour in that period and yet it sustained also gaming to some extent like for 20 min. or so and again in night was connected to my wifi yet it survived this huge load.
So around 1 am in midnight it got drained completely and then I put it on charge in switched off mode, at around 4:45 am in morning I removed it from charge with battery completely charged(100%) and then I switched it on and went back to sleep. After 2hr i.e. at 7 am when I woke up the battery went down to 89% without a single use(I didn't even unlock the phone after I switched it on) almost 11% battery drain is seen in stand by mode and that's the point of concern.
So one thing is for sure the drain is not because of any application also in last few days it's my observation that the place where I keep my mobile used to be covered properly under HSDPA n/w and always use to have H or H+ as the network symbol but now it shows E and it might be switching to and fro and I guess that might be the one reason for the drain.
Kindly share your view on this and also your guidance if you have any

I had the same issue except, in my case when it reached 25%, it dropped very quickly. So I calibrated my battery and its working fine now. This app is available in play store free of cost but you have to rooted to use it.

Hit thanks if I helped.
People are in search of an extended battery which fits the original case.
While I know that most of these batteries are scams, I am in search of a brand who can deliver a bit more power to our beloved note 3.

Today I tried the MPJ 4500 mAh battery with NFC (it works).
I used a free app from the play store to fast discharge all the batteries.
The MBuyNow was tested twice, the first test has been done on the first discharge of this battery, it came with 60% and it charged itself from 58% to 100% in 1h and 13m with the stock charger. The second test was done after 10 cycles of charge/discharge.
The stock battery was tested once in order to have some comparables.
The MPJ battery has been tested one time, after 17/20 cycles of charge/discharge.
So, let me describe the four tests:
Common factors:
- Both batteries were charged to 100%, then I rebooted the phone, unplugged and plugged again and waited the confirmation that the battery was really 100% charged;
- Fast Discharge has these settings: "High CPU load; Camera Light; High brightness display; GPS receivers; Operated Vibrator; Network Connection."
- As soon as I unplugged I started the "Fast Discharge" app with everything flagged on but "operated vibrator".
- I never moved or used the phone; I forced h+ network only (wcdma); accounts syncs were off.
- Phone has been in the same spot for all the tests to make sure that network and wifi signal was as costant as possible.
1) Mbuynow battery: - I received 13 whatsapp messages, 21 instagram notifications and 20 messages on facebook;
- Battery drained from 100% to 5% in 2h 2m and 9s.
2) Stock battery
- I received 14 whatsapp messages, 11 instagram notifications and 25 messages on facebook and 1 gameloft notification;
- Battery drained from 100% to 5% in 2h 17m and 53s.
Ok here comes the second and last test of the MBuyNow battery.
3) Mbuynow battery 2° test after 10 charge/discharge cycles:
- I received 29 whatsapp messages, 60 instagram notifications and 41 messages on facebook;
- Battery drained from 100% to 5% in 2h 11m and 42s.
Today I tested the MPJ battery.
I just finished the test with the MPJ battery, so let me explain what I did.
I turned air conditioning on in order to reach aprox. 20°, which was the temperature back in January when I tested the previous batteries.
Moreover I followed all the rules I used in my previous tests: same app to fast discharge, same conditions, same networks, same place ecc..
The only thing that has changed is that I am on X-Note rom, but on stock kernel.
Before writing the results, I have to say that the battery discharged to 5%, than I removed it from the phone in order to weight it. When I powered the phone on, the battery indicator showed a 15% battery remaining. I decided to run the test to discharge the battery from 15% to 5% once again. This behaviour happened another time and the battery was at 8% so I ran the test again. This means that I have 3 results, 2 partials and 1 total.
4) MPJ battery after 17/20 charge/discharge cycles:
- I received 19 whatsapp messages, 2 gmail Notifications and 18 messages on facebook;
- Battery drained from 100% to 5% in 2h 11m and 52s.
- Battery drained from 15% to 5% in 11m and 13s.
- Battery drained from 8% to 5% in 3m and 13s.
If you consider the total time, the battery lasted 2h 26m and 18s. If you want to consider only the first discharge the battery lasted 2h 11m and 52s. If we do a simple calculus, we can say that if 95% of the battery lasts 131 minutes, then 10% of the battery should last aprox. 13 min, which is not far from the 11m duration that the battery had in the second discharge.
After the test I weighted the three batteries and all weigh aprox. 50gr with 2gr of deviation.
When 100% fully charged the stock battery weights aprox 61 gr while the MBuyNow aprox 58 gr with 2gr of deviation. The MPJ weights 62 gr.
This is the link of the store I bought the MBuyNow from: http://www.ebay.it/itm/291005429861?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

This is MPJ official site: http://www.mpjbattery.com/mpj-4500m...sung-galaxy-note-iii-3-n7200-n9000-n9005.html
Below you will find some pictures and screeshots, I think I mistakenly deleted the screenshot of the first mbuynow test and of the 3rd discharge of the MPJ, but I was smart enough to write everything down on paper!
In conclusion, this kind of test is not really precise in terms of mAh but I think that it can give us a way to compare these batteries with each other.The MPJ battery does not clearly have 1300 (40%) mAh more than the stock battery, but 8/15% seems to be a reasonable amount. The MBuyNow 3900 mAh battery can be considered a good - cheap - replacement for our note 3, but it clearly doesn't add any extra mAh or hour of usage.
Any other battery you want me to test?

Hey guys, I have done more than 5 cycles of full charge/discharge.
To make the next test as clean as possible I also made a fullwipe and waited 5 cycles to accomodate android to the "bigger" battery.
Later today I will run again the test, but after a week I can already tell you that the battery has not perfomed better.
It's probably around 2900 mAh, which is not different from the 3200 stock battery, but really far away from the 3900 mAh they advise for.
Anywaymy opinions might be placebo, so I am defo going to run the test later to give a last chance to this MBuyNow battery.
Keep us updated

I remember when I had the Note 2, I bought a replacement battery that supposedly had a higher mAh than the stock one. When I peeled back the battery's sticker it was the exact same mAh as Samsung's battery so it actually didnt hold any more power. I'm wondering if it's the same situation in this case. Actual battery being the same, but just the label claiming to be higher mAH

Nope, I checked under the sticker and there is just a normal metal plate
People dont bother with MPJ, duds too! I brought one for S2 and only got like 75% what they claimed
I just sent MPJ an email asking for a battery sample in order to test it out.

I decided to make the jump and ordered the MPJ one. I will update this thread with the tests as soon as I do 5 charge/discharge cycles
I received the battery 5 days ago and I am on my 3rd cycle. I will make the test on friday or on saturday, as soon as I reach 5 full charge/discharge cycles.
My first impression about this MPJ is that it isn't 4500 mAh, but it's lasting a bit more than the stock one. I don't know if it's a placebo effect and only the real stress test will say the truth. But I have to be honest: when I tried the MBuyNow battery I wasn't experiencing any better result, while now I feel that my phone is lasting a bit more.
Check this topic on friday / saturday for an update, we might have a surprise and a winner!
For three years I've used MPJ as my default battery (N1 and N3) and I've always found them to give me, say, 10 to 20% more than stock. After all this time, I don't think it's placebo. I notice the difference even when I forget which battery I have in.

The test is conducted with the screen powered on. The results in terms of time that you see are exactly the time that the screen as been on. From the first post you can see that the MBuyNow reached 2h and 11m, the stock battery 2h and 17m and the MPJ 2 h and 26m.
This is my MPJ usage :
Currently using with amazing Echoe ROM.
Edit: just my print at this moment.
This is a good battery at least for me.
I had been using it for 5 months.

Super thanks, this comparison helps a lot.
Since you asked which other batteries people would like you to test, I'd definitely like to see how the mugen battery performs. Any chance of you reviewing that one?
Hi,
Long time lurker - the community has really helped me many times in the past. Thank you.
I now have an issue with my battery in my i9300. Phone and battery are 22 months old. All stock (updated to 4.3).
Phone gets charged every night from 10pm to 6am. Usage has been constant - no new apps added in last year.
Until 2 months ago, the phone would have 25% to 35% at the end of the day having started at 100% each morning
Then it started to drop to 15-20%. I thought - hmm - battery is aging a bit.
Then, in the bast week, suddenly, I get a max of 4 hours use, then battery dies. It recharges to 100% in one hour (I use a 10W charger) and then lasts again for 4 hours.
The battery is not bulging or showing other signs of being defective. There does not seem to be any apps that are using unusual cpu %. Phone is responsive.
My questions are:
1. Is it normal for a battery to suddenly degrade like this? I thought the Li Ion batteries degraded at a constant (20% per year half life) rate.?
2. Is using a 10W charger damaging to the battery (stock is 5W) ?
Thanks
Mark
1. Yes, two years old is ancient so replace it now.
2. Rating of charger is irrelevant, the charging circuit in the phone decides what the battery gets.
Definitely replace the battery. When I was using the Galaxy S3 after 15 months of buying it, the battery was simply horrible. It wouldn't last even half a day. I bought a new battery and it is much better.

I think that 22 months for a phone battery you charge every day is "normal"... that's why I bought a phone with a emovable battery
