I've seen a lot of unanswered questions about the real difference, other than the price, between the 1200 mAh (original) versus the 1400 mAh (aftermarket)
If no one has any objections, i will try to evaluate the power drain time with my Socket SD WiFi card inserted. I will also include pictures of the actual Batteries and the place where I bought the 1400. I will do that tomorrow evening.
Hope this unscientific little test will help or, at most, entertain you.
I swap between a 1400 and a 1200 mAh battery in my xda2i depending on which is charged and I can quite honestly say I never know which one is inserted. Theres very little noticeable change in length of useage time from the 1400 to the 1200mAh battery.
Obviously the 1400 has 1.17 times more capacity than the 1200, but i'm saying in real world use... you don't notice it.
I guess what you would expect to find is if you got 5 hours (just as an example) with the 1200, you could realisticly expect to get almost 6 (5.85) out of the 1400
Test is starting
Test conditions:
* Fresh soft reset for each test
* Week-old hard reset (good ol' format)
* i-mate Pocket PC Phone Edition
* ROM: 1.72.00WWE
* Radio:1.18.00
* Extended ROM: 1.72.800
* Socket SD WiFi (H/W 2.1)
* Socket Driver 142 G
Today screen stuff:
* Date
* Owner Information
* Calendar
* WeatherPanel 2.3.1 (3 cities, automatically cycle cities, update interval at 30 minutes)
* Inbox
* Tasks
* Money
Parameters:
* Backlight always on
* Automatic call forwarding to my landline activated
* Almost perfect Wifi Signal and Link quality
* Very good (4/5 bars) and stable GSM connection (GPRS disconnected)
The two subjects:
* Original battery made in Japan (1200 mAh)
* Aftermarket battery made in China (1400 mAh)
Methodology:
* Unplug the previous battery
* Insert the SD WiFi card
* Plug in the test subject (fully recharged battery)
* Close the back cover (i-mate should power on at this time)
* Start the timer
* Wait for the low battery warning (10% left)
* Stop the timer
Additional notes:
The original 1200 mAh battery is in daily usage since February 2004 and the aftermarket battery since December 2004: the results may be different with brand new ones. I recharge the battery plugged in my I-mate every night. My i-mate is plugged in on work hours every weekday (sometimes in the week-end). When I'm in front of my home computer, the i-mate sits in its desktop stand, charging (and synchronizing). The batteries were never deep-discharged.[/code]
I dont know if this test is going to be very accurate if one battery is almost a year older than the other
luckily, my 1400mAh is about a week old and my 1200mAh is about 3 weeks old... i stand by my observation that theres little difference in REAL WORLD useage time
Well, actually, that's what I think. That'S why I put a complete description of my setup. But I don't have a new one handy.
Can anyone borrow me one in Quebec City? hehe.
Anyway, this test will tell me wich one of my two batteries is the best right now. My feeling is that the original 1200 mAh i-mate battery will last as much as the aftermarket 1400 mAh. If yes... well I won't buy another 1400 mAh from this shop again :wink:
if it will not last the 16.6% longer then it's kinda false advertising
I think the "stated" capacity has a caveat - depending on the method used to determine number. I'm no expert, but I suspect if you play video vs wi-fi will probably give you a different mAh number.
So a lot of the after-market products will claim, at the very least, an identical capacity compared to original, else you won't even look at them.
I have both, with a much older 1200 and new 1400, and can't feel any difference between them. Never did an outright test, but never noticed any difference.
One way to measure *possible* capacity is to weigh the battery. If they weigh the same, capacity when new is going to be very similar.

If you want to run test, you can keep playing video clips with both batteries and compare.
Weighing probably is less indicative because they may use different cells.
What do you think?
Hello, recently, we have hear many stories on the news about phones battery's explosion. After doing some researches on the Web and using some common sense and basic knowledge, I know that voltage range and temperature of the battery are strongly related to the overall condition of the battery. Therefore, I just want to ask, generally, for a 3100mAH battery (for Note 2), what is the secure voltage range and what is the secure maximum temperature threshold? Also, what are these factors for the 6500mAH (extended battery for Note 2)? note: I personally don't think that these factors vary with the battery capacity, but I just still want to ask in advance... And I am talking about a lithium-ion battery

BOOST BATTERY 10% IN GALAXY ON8
I was able to find a workaround for the battery percentage:
1. FIRST Get your battery capacity!!!
$ adb shell cat /sys/class/power_supply/battery/batt_capacity_max
942
2. Calculate your 100%
942** 1.1 = 1036
MAX=1070
DON'T PUT IT
PUT BELOW 1050 OR 1050
3a. Charge battery fully (UI will say 80%):
Use your new 100% value in place of my 1036!!
adb shell
$ su
# echo 1036 > /sys/class/power_supply/battery/batt_capacity_max
3b. To revert back (and see actual %):
put your old value in place of my 800 here
adb shell
$ su
# echo 942 > /sys/class/power_supply/battery/batt_capacity_max
Warning:This is not persistent across reboots (but could be implemented as such)This does not change the fact that your battery meter will say 80%This confuses your phone into thinking the 80% limit is higher than it actually isThis could be harmful to your battery life, battery condition, and battery operationThe Control Chip on the battery itself should prevent any unnecessary charging from occurringI'm just a guy on the internet, don't mess with your phone unless your are willing to pay for any mistakes.
How this works:The Kernel reads the battery percentage from /sys/class/power_supply/battery/capacityWe make the maximum battery capacity increase by 20% /sys/class/power_supply/battery/batt_capacity_max (the commands above)Kernel reads the battery percentage from /sys/class/power_supply/battery/capacity again and its now 20% lower because of capacity calculations (percentage = used capacity / batt_capacity_max)Kernel lets the charging continue to 80% which is in actuality 100%
FAQDoes this work?
Yes this works. The explanation is above. Succinctly, these commands trick your kernel into thinking the 80% limit is at 100% of the battery.
Shouldn't we be adding 25% to reach 100% of the battery?
While this is correct, I tested a few percentages and noted that 20% increase will reach 99% battery on my phone. This does not mean it will for everyone.*PLEASE BE COGNIZANT OF OVERCHARGING
This isn't working for me, why do the values change?
You*must*be a superuser in the terminal for these commands to stick. They do not stick across reboots.
This still doesn't work, wah wah wah. I wan't 100%...
I am trying to help the community. If you don't want help you can keep the 80% charge. Multiple people have said it works. If you don't want to try it don't. Blindly saying it doesn't work is only poisoning the well.

Howdy,
You might remember me from the Xperia Z2 or the Xperia Z. I've started playing around with Android on my old Sony Xperia X10i and i've always liked fiddling around with too much data and thoroughly testing what i own in order to fully understand it.
Lately i've been active in the HTC 10 Subforums but since the Battery started going bad i've become afraid of the phone dying on me and i got this really good deal on the XZ2. So here i am back at Sonys.
So... this thread is mainly for me to keep my findings sorted but you might also find some interesting things here.
If you take a look at my older threads you'll know what to expect
What's new with the Xperia XZ2?
Well.... Android 8.0 with SD845 and 4.9 Kernel... no more Interactive governor. We got EAS built in an use SchedUtil. While it is possible to modify the behaviour of SchedUtil via SchedTune it's nowhere nearly as complex as Interactive or different governors.
Trepn Profiler doesn't report Battery Power anymore... while Trepn Profiler has been partially broken since Android 6.0 it did work kinda fine on the SD820 devices even with Android 8.1 and custom Kernels. (except Load%) Even though it was limited one poll per 30sec. While on the XZ2 only estimated Power is available. Which does not work due to missing CPU load.
Benchmarking:
Powerdrain: Find out how much the Phone is using under specific circumstances.
Charging: How fast does the Device charge from 1% to 100%
Throttling: Analyzing Thermal and Powerlimit Throttling
Benchmarking Apps:
Repetitouch: To create custom Benchmarks that simulate normal everyday usage.
BatteryLog: For Charging Benchmark, Voltage and Battery% per Minute
GameBench: For FPS in games. (Make sure you deactivate Screenshot function for HTC10)
Benchmarking Hardware:
YZX Powermonitor: USB 3.0 QC3.0 4-13V 0-3A USB A Male-> USB A Female Powermonitor that measures Voltage and Current passing trough.
I'll update this Post when new infos are available...

First thing we see is the max Voltage.... this phone is fully charged at 4,331V Okay? Guess that's the new kind of Battery. I'm used to see 4,4V
After 40 Minutes when the battery reached 40°C and 60% there is Thermal Throttling. If you take a look at the HTC10 Charging you can see the CCCV breaking point this does not happen here, it's simply reduced from 11W to 8W which does indicate throttling. It's only after 117 Minutes when the Battery reaches 4,33V that you can see the expected curve...
This has to do with the new Qnovo Charging Technology. Nice read on Qnovo Charging Technology...
In the far future when my phone found out when i charge it over night i'm also gonna measure the Battery Care in action i wonder how slow it charges if it has the time.
Oh, and i'll have to Try with Another QC3.0 Charger. While the UCH12 is QC3.0 and PD2.0 compatible even the Old Sony Chargers said 1.5A but only charged the phone with 1A....
just some ramblings to not forget....

To Properly show these Values i've modified the adb reading scripts i've found somewhere else on XDA...
You simply start the .bat file when connected via ADB... either trough USB, or connect phone via USB type "ADB tcpip 5555" unplug, when in WiFi use adb connect 192.168.1.XX:5555
Welcome back! ^^
Thermal Throttling & Task Migration / Load Balancing
When i first used this phone i tought i'd have Endless power in my hands, so i couldn't resist using it ALL. Started CPU Load Generator app and saw that even with 8 Threads fully loaded the phone does not throttle down CPU....
Sound awesome huh? Even the Temperature wasn't getting that hot. Coooool... (pun intended)
But i was a tiny wee bit Skeptical. Could it really be? So i've decided to use my USB Powermeter and charge my phone to 100%. After a while the phone kept using the same current. 0.255W to be accurate. (With Screen Off and WiFi connected)
using a Full Load i could see all CPU cores staying at the max Frequency.
But.... the wallcharger did say something different!
Not even a Full Minute! While it does peak at 8W it falls down to a sustaineable 4W rapidly. (Even drops to 3.5W Later on...)
So What's going on here?
Using Snapdragon Profiler with ADB over WiFi i've tried different Load Scenarios, 1-9 threads and 16 threads.
1 Thread:
You can see the Thread jumping between core 5, 6 and 7
2 Threads:
With 2 Threads core 4 is also used this time
3 Threads:
with 3 Threads Core 7 is not being used anymore... throttling? The phone is trying to reach a sustaineable temperature of 60°C by limiting Big cores to 2.4ghz
4 Threads:
While core 7 stays offline we see the small cores being used, and a throttling to 2.4ghz on big cores.
5 Threads:
While it did cool down enough to go back to the big cores previously, now it stays on small cores. Also 2.17ghz on big cores.
6 Threads:
7 Threads:
Dropping to 1.84ghz on big cores
8 Threads:
Aaaannndd... here is the magic! 2.8ghz on big cores! Somehow the phone switched to another throttling method than frequency.
9 Threads:
While we did see some slight CPU frequency drops with 8 threads, they're all gone with 9.
16 Threads:
Exactly the same as with 9 threads.
Sadly Snapdragon Profiler does not show BatteryPower on the XZ2 So it seems plugging to the WallCharger is the only way to figure this out.
I'll have to redo tests when my phone is fully charged and see if i can get a consistent powerdrain.
Edit: Update: Android P Beta.... Dev Preview 2
Starting with 4 Threads...
Core 7 does NOT get turned off anymore.... But you do see a small task migration as soon as 68°C are hit. Small cores get more load.
Looking at the Performance you see a gradual degradation, and not big spikes like before.
With 7 Threads:
We can see Thermal Limit has been increased to 72°C
The Performance drops really fast to 85%-90% but manages to stay there for a long long time. i'm really impressed.
Edit:
Absolutly nothing new with Android 10 (Again 8 Threads)
Powerdrain & Thermal Throttling
Okay... here we go... Wallcharger + Snapdragon Profiler...
First i've charged my phone fully to check Idle drain. Around 0.3W check.
About GPU testing:
You see the Idle 1.2W Powerdrain at the beginning? That's because Snapdragon Profiler is connected via ADB over WiFi. Quite a lot compared to the 0.3W Idle...
The first few Peaks until 12 Minutes are a failure because i've accidently started the sublevel Benchmarks^^
The first real Peak to 5.4W is a CarChase OnScreen.
The 1.7G on Clocks/Second is a reading error, normal Max is 710Mhz.
You can see the Temperature reaching 66°C and throttling starts, GPU going to 600Mhz, also Big Cores limiting to 2.17ghz.
The 2nd Peak is CarChase OffScreen.
You can see the big cores dropping in Frequency pretty early. GPU maxed out at 710mhz, until the phone reaches 68°C. GPU throttles heavily, and Big cores are going Offline putting the Load on small cores.
Which caused a drop in Powerusage from 5W to 3.7W
The last Peak is Manhatten OffScreen.
When Throttling starts at 68°C GPU drops from 710mhz to 600mhz and task migration from big to small cores.
The Powerdrain is reduced from 4.4W to 3.9W
About CPU testing:
Well.... that didn't work as well as expected... In the Powermonitor graph you can see i've used CPU Load Generator started with 1 Thread, and added 1 more after 1 Minute, until i had 4 threads.
Admittely the phone was already 45°C when i started this test... therefore i've already had throttling before i even started.... But well.... i've expected more...
The same peaks that are visible in the Powermonitor graph are also clearly visible in the temperature graph on Snapdragon Profiler.
So even if the phone is throttling, it allows Burstpower/increased thermal limit for new tasks, to reduce lag. Pretty neat.
Edit: Here we go... on a cold device:
As always, until Minute 1.2 is pure IDLE, from 2-2.7 is whit ADB over WiFi and Snapdragon Profiler connected.
At Minute 3 you see the start of the first Task. Using around 3.3W
At 4.2 you see the 2nd Task starting, generating 4.4W load
At 5.2 the 3rd Task starts, using up to 6.3W but shortly after (timestamp 225s in the graph below) the phone reaches 68°C and starts throttling. Load drops to 5W. because the continous Load of 5W is not sustaineable the phone throttles down to 4.1W (timestamp 245s)
Tt 6.2 Minutes the 4th Task is started, which generates 5.2W, this causes the phone to get almost 68°C again (timestamp 275s) and drops powerdrain to 3.3W, the phone cools down to about 60°C (timestamp 295s) and stop throttling, therefore peaking to 6.1W and rising to 68°C again in 10 seconds. Trying to limit powerdrain to 5.2W for the next 5 seconds fails, and task migration kicks in turning core7 offline and pushing load onto little cores. Limiting Big cores to 2.4ghz and using 3.9W
(timestamp 0s equals 2 Minutes on the other graph)
Edit2:
So what does that mean for Performance?
I've used the App CPU Throttling Test to create a workload and also Display it's performance. Here you can see 3 threads at work. Full Performance 125.9GIPS
The 2 Minute run does not throttle, Snapdragon Profiler proofs that
Using the app with 7 Threads causes throttling twice. But again, all cores are shown at full frequency.
Using Snapdragon Profiler we can see the phone throttling at 64°C (timestamp 447s) and later on at 60°C (timestamp 490s)
The performance drops from 125.9Gips to 104.9Gips. Nothing in Snapdragon profiler would indicate that.... CPU frequency stays the same and Load is also equal.
These graphs are such a pain
I have no clue where the Thermal Limit is on the P Beta.... but it seems to be quite high!
(click on Image to get redirected to interactive Chart from Google Sheets)
(The Drops are when i stopped testing and changed from 8 to 7 to 6 threads)
panel0-backlight thermal-devfreq-0 thermal-cpufreq-0 thermal-cpufreq-1 thermal-cpufreq-2 thermal-cpufreq-3 thermal-cpufreq-4 thermal-cpufreq-5 thermal-cpufreq-6 thermal-cpufreq-7

0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0
There is NO throttling due to Task Migration, thats what Snapdragon profiler said, and the value in sys/class/thermal/cooling_device0/cur_state proofs this. As you can see in the example above, they stayed at 0 during the whole test.
Which is nice to know, since now we're certain Performance throttling does not happen due to a value in thermal/cooling_device*
Edit:
Oh.... not sure if this is a P feature or happens on Oreo too... gotta test...
But when you reach 5% Battery big cores shovel all Tasks to small cores, therefore frequency drops to 800mhz and performance takes a HUGE hit.
This time we see all 4 big cores reach a value of 24 on sys/class/thermal/cooling_device* for thermal-cpufreq-4, 5, 6 and 7.
Edit 2: Thermal Throttling on Android P (dev preview 2)
Yeah... i need way more patience.... Did another test, this time while charging, so we have power Measurement!
We already knew Thermal limit was WAY higher on P.....
(interactive Chart...)
Because this was using External Power from Wallcharger the battery did not heat up as fast because it was not used. Took 10 minutes for the battery to reach 43°C while the starting point was about 32°C
What we did not know... the PowerLimit is different too!
on Oreo it peaks at 8W and then rapidly drops to 6W and even lower to 4W when the Limit kicks in.
Thanks to the bigger Thermal Headroom we have in P it only peaks to 6.5W and drops to 5.8W in 1 minute but after that it continuously falls from 5.8W to 5W in 10 Minutes! Seems like it manages to stay at 5W. Oreo couldn't handle that.
You Remember Qnovo Charging on the XZ2 ?

Well... it's not present in Android P Dev Preview 2.
We still have the typical CCCV point
But instead QuickCharge 3.0 is doing a good job in scaling Voltage.
Charging is fast, 105 minutes to 130 Minutes... but with Qnovo you have 93% at 105 Minutes, who cares about 7% If you have way better battery live.
Sadly Bluetooth Broke down after 70 Minutes.... oh well you can probably imagine what happens from minutes 70 to 130 right? ^^

Coming from OnePlus, I'm not impressed at all. My 5T could do 0-93% in only 60 mins. Almost twice as fast... Old OnePlus phones didn't seem to suffer from battery degradation after more than a year either.

Firstly Sony is limiting itself to QC 3.0. Secondly seeing as higher end phones all pack high quality batteries, they all suffer little degradation in the first place. Sony's method might make them last even longer. Come back in 2 to 3 years time and compare the battery health before saying you are not impressed. Not everyone is rich like you people to change phones every year or less. There are people who think about really long term usage and this should benefit them considering how batteries are non user replaceable nowadays.

I said that because my friend is still using his OP3 and it's been two years. His SOT is still largely similar and he use Dash charge all the time.
And no I am not rich. Rich people buy iPhone.

one thing worth noting when it comes to battery life
What killed my battery on my Z1 (I replaced it twice) was doing nandroid backups with TWRP, I believe part of the problem is that all the OS battery control and protection is not running when you boot into recovery and it causes extreme overheating, it is definitely something to be aware of and IMO destroys batteries
Charging Android 10
Nothing much changed For the good or the bad ^^
Aftermarket Battery Tests
Aftermarket Battery Tests
Because i was unhappy with the Batterylife of my XZ2, it was nowhere near where it has been 2 years before, i decided to open my phone and replace the battery!
Opening your phone seems kinda easy, so no big issue. In theory... in practice you need to be aware of 2 important details.
You need new Glue to close it again. Afaik Witrigs is the only seller of that.
Be verry carefull on the bottom part. If you go too dep you will cut your Display cable and need to buy a new LCD for 35$. I'm speaking from experience....
How to test the battery?
Because the connector of the battery is proprietary and extremely compact you can't plug the battery directly, so i had to make use of the USB Power Delivery function to draw 5V out of the phone.
The Phone was in Flight mode with screen off, to make sure no other services use the battery. Then i connected a Load Generator i bought from aliexpress. Drawing 5V 1A my 2.5 year old battery lasted 1h33 min and gave out 7.6Wh
Original Battery:
Which has been in use for more than 2 years.
7.6Wh - 7.8Wh Obviously i did 2-3 Tests to see if i get the same every time. And it was always around that.
Hsabat 4300mAh Battery:
Bought from Aliexpress for 13.- Looks pretty decent. Is utter crap. As one expects.
First charge gave 7.3Wh, Second charge gave 5.6Wh and third charge gave 6.5Wh Not something you want to put in your phone.
Witrigs Battery:
Since i bought the glue there anway, why not just get a battery for 9$ and test that!
It looks bland (black) but hey... who cares as long as it works.... right? it works?.... well yeah...
First charge gave 7.3Wh and the others were also around that. "New" Battery? i Don't think so...
Phonedepot
Because i was disapointed that my old 2.5years harshly used battery has better capacity than **** i bought online i went to a swiss shop which has quality batteries... well yeah... at least is supposed to: Phonedepot.ch
It's more expensive but has faster shipping (as its close by) and the quality of the battery looks way better from the ouside.
I managed to draw 7.4Wh - 7.5Wh
Conclusion
Well... it was obvious before i even started.... i just didn't want to believe it.
Aftermarket batteries sucks. All of them!
Simply replacing your battery to get better batterylife is a dream. If youre battery broke down completly a replacement can help out, yes. But not if the battery is ageing normally.
This is extremely useful info, thank you for the tests.
Yeah, so this is a problem. As I mentioned earlier, I didn't bought any of those "new" batteries or aftermarket ones. All of them are a low quality piece of garbage so unless your battery is dead, literally, I wouldn't really buy these. This isn't any help from me and I am aware of that. The problem is, you can't really buy any genuine battery from anywhere. LG has a lot of genuine replacement parts and you even can buy from them directly, or from samsung. I tried looking on aliexpress but there are "replacement" batteries that are obviously fake or "original" that have the same serial numbers printed on them.
Official Battery Test!Because i really couldn't let it be i wen't and bought an official Sony Battery.
Where do you get a Official Battery you ask? There is an Official Sony Homepage that lists Repair Centers. Here in Switzerland Sertronics is the official Repair center. Mailed them with the Part number and Foto of my Battery and got a quick answer.
28.- is an extremely fair price. the 16.- shipping are somewhat annoying.
So i got an Official Battery which Looks WAY better than the other ones.
Looks pretty much the same as my Original one right?
So let's get into Testing...
As Before I've used my Discharging Tool via USB Type-C with 1A draw the 5V dropped to something like 4.85V so 4.85W draw was used. Phone in Flightmode with Screen off to have almost no internal power usage.
Sadly i had issues with some kinda power Saver which killed the USB Power drawing at 10% Battery sometimes....
Run:Time to 10%Wh at 10%Time to 0%Wh at 0%Stock Run 11h 28min7.1Wh--Stock Run 21h 29min-1h37min7.8WhStock Run 31h 29min7.2Wh--New Battery Run 11h 22min (16%)6.6Wh (16%)--New Battery Run 21h 27min-1h 38min7.9WhNew Battery Run 31h 29min-1h 38min7.9Wh
Works pretty much the same. You can see the Voltage Drop at the end is not THAT bad as with the Original Battery. (Yes, both of them we're used until the phone did an Emergency Shutdown due to low battery, shows 0% in the Log)
Because these Results aren't really that good (And Yes, i've plugged the new battery and used my phone for one week to let it acclimate, i also did two Full resets with the new battery, one with newflasher) i've checked the Battery test in the Service Menu.
It truly is no good. I've bought a "Typical 3180mAh" battery that has a minimum of 3060mAh and then it offers 2654. My old battery was showing something around 2700mAh the last time i checked.
So yeah... it is a fully working as intended Battery without any flaws... BUT the capacity is WAY to low.
I will contact the repair center from Sony and ask what the think of this.
Judging by the marked numbers on the replacement Sony battery, it was manufactured between April 4th and 10th 2020 (20W18 - year 2020, week 18). So you received a one year old battery. I also have some experiences with batteries manufactured around that date (20W32). Very poor results: 2200 mAh at first charge, then goes down to a consistent 2000 mAh for all other ones. XZ1 Compact here.
