As a project in my Statistics course we are asked to develop and carry out an experiment. Rather than do something conventional I felt pressed to do something that would actually be useful to myself and potentially the community.
-A comparative experiment of radio stacks' effect on battery usage will be done.
Now I realize there are many confounding variables that effect battery drain that are equally as important, location, usage, brightness, ram load and user use habits : however for the sake of the experiment I wish to see for each user how their battery drain changes based on the radio in their area on their usage. Because each users results will be directly compared with their own many of these confounding variables will be minimized as much as possible with such a short time frame to test.
The experiment will call for any available HTC Touch Pro users (World wide) starting May 18th to flash the official radios, each day trying a different radio and tracking the battery drain.
The current plan is to use the official released radios at
(Including the ATT Test rom radio but not the newer 1.14.25.05 due to issues and bugs confounding the results even more)
- Radio - Day of Trial - Date - My Resulting Percentage at end of day
-1.12.25.19 - Benchmark / Comparison test - May 18th - 40% at midnight
-1.02.25.11 - Day 2 - May 19th - 6%
-1.02.25.19 - Day 3 - May 20th - 15%
-1.02.25.28 - Day 4 - May 21st - 45% (gasp)
-1.08.25.20 - Day 5 - May 22nd - 3% (Battery Change out at 10:30pm) 87% on battery 2 - total - -10%
-1.01.25.16 - Day 6 - May 23rd - 14%
-1.02.25.32 - Day 7 - May 24th - 5% (Battery change out at 9:30pm) 51% on battery 2 - total - -44%
Just got a Touch HD - Had to take 2 days off the trial to play with the lovable device.
-1.02.25.27 - Day 8 - May 25th - (May 27th) - 3% (Battery Change out at 10:30pm) 98% on battery 2 - total - 1%
-1.02.25.31 - Day 9 - May 26th - (May 28th) - 43%
-1.11.25.01 - Day 10 - May 27th - (May 29th) - 10%
- End of Trial - For me -
I will wait a while to collect all available data from testers then perform the statistical analysis.
Download Radios Here
Conditions for testing:
Because each user is unique in exactly how they use their devices, 3G / 2G, Wifi, Bluetooth, GPS, I only ask that the usage be relatively consistent throughout the trial. As long as you are consistent with the other things draining your battery we can see exactly what it is that radios drain.
Each evening anyone willing to participate in the experiment will flash a new radio and track the battery drain over the following day.
In order to track battery usage, the performed method will simply be recording the remaining battery life percentage at the conclusion of the day. (usually a selected time by the user) This is due to no battery tracking application freely available that efficiently tracks battery levels without interrupted normal usage or battery life.
I apologize for the short time frame that has been created, however the project was developed months ago, yet the teacher simply dumped it on us to get the actual experiment done next week and I am truly hoping I can stir up enough interest and enough volunteers to get the data I need.
Please post if you have any interest in the project, wish to volunteer, or have a suggestion for which battery app to use.
I need volunteers and this is information that is helpful to everyone, so please take part and please help out.
If nothing else, I will post at least my own results to this little experiment.

Started a day late, hope it's not a big deal!
I second the attendance on this
Tell me where to locate the radios and where to submit results, I'll be there. count me in.
Thank you for the immediate support. As I said in the post this will attempt to begin Sunday evening where you will flash the first Radio and continue Monday like normal, then at the conclusion of the day simply record the remaining battery life percentage.
Try to keep the start and end of your day consistent and ensure devices are charged to full every night. This may mean simply recording you battery level every night at 8pm rather than waiting until you head into bed to keep the timing consistent.
I hope anyone interested signs up as well, as the more data the better.
Anyone can sign up for the trial, if they have a Touch Pro or a Fuze, doesn't matter. In fact they can even join up halfway through, they will simply need to continue the trial to include the missed radios.
Tomorrow will begin the first day of the test, as the comparison test we will begin with the radio that is considered to be the best by many. The ATT test rom radio. 1,12,25,19
All radios can be downloaded from the radio thread
http://forum.xda-developers.com/showthread.php?t=439566
This thread includes downloads for all radios and flashing instructions.
Reporting for duty
I am willing to participate in the survey...Should we recharge if it doesn't last the whole day and document the time it went dead?
Yes, if your device does not make it through the entire day on one of the radios. document the time and either recharge to full (if not full record the percentage) or swap out batteries (to a full one) and continue like normal. then doccument the remaining percentage at the end of the day.
Tomorrow begins day one of the trials, so if we could all flash to the ATT Test rom radio
1.12.25.19 and charge our devices, we can begin this whole thing tomorrow morning!
Simply post your daily results in the thread, send them to me in a PM, or find me in the IRC channel #XDA-Devs under the name NonPlayerChar and message them to me. You can do this after each day, or keep a record yourself and send them to me whenever you find it convenient.
.. wish i could participate
buti cant even flash rom's even though i can tweak everything else on my phone. and i carry two batteriez... im definetly gonna keep reading this topic.
My first two days results
1.12.25.19 Day 1 May 18th 62% -- 12hr timeframe
1.02.25.11 Day 2 May 19th 47% -- 12hr timeframe
I have to add if you noticed that I only kept the phone on for 12hrs as I turn it off at nite before I go to sleep to avoid the ex-wife from texting in the middle of the night. If you would like me to test for 24hrs. please let me know and I will find a way.
Both test periods were with push email enabled (HSPDA on) and identical usage.
I have the newest 1.14.25.05 and no issues here, i can report if needed
Great results so far, I would like thank everyone who is participating.
Fjmora992000 : Great results - No your time window is perfectly fine, as long as it is consistent.
Mine goes from about 7am to 12am the next day, so a 17 hour window.
I am seeing similar results with 1.02.25.11 compared to 1.12.25.19. Although, if the drain continues as expected, I may be exactly 0% at midnight.
Bowdowntozoltan : Great to hear it, I may try out the new radio soon as the trials end. If you would like to participate in the trials, any effort would be appreciated, however for any data to be relevant you would need to try the other radios on your device as well. This would be much appreciated, as anyone knows, a large sample size is ALWAYS* better. As I said before you can simply continue as scheduled with the planned radios then make up the previous radios after the end of the trial.
*(A large sample is almost always better, except for when a sample is more than 10% of any given population... this causes conflicts with independence however... we will not get into that)
Final results.
Sorry for the delay, I've been working a bit and trying to settle into the new routine. The test was a gruesome one, many variables led to an ackward result. I think I'll redo test again and see what comes of it.
1.02.25.19 - Day 3 - May 21st 40%
1.02.25.28 - Day 4 - May 22nd 47%
1.08.25.20 - Day 5 - May 23rd 55%
1.01.25.16 - Day 6 - May 24th 45% very unstable
1.02.25.32 - Day 7 - May 25th 38%
1.02.25.27 - Day 8 - May 26th 53%
1.02.25.31 - Day 9 - May 27th 60%
Thank you for the results.
I had some terrible instabilities with a few radios myself, causing horrible lockups and simply all around poor system performance, however I've found it best to simply work through them.
Can anyone specify how long you have to actually BUY the phone after receiving your invite? From reading the OPO forums, I've seen 30 days and then your invite goes to next in line and then now I'm reading you only have 24 hours?
I don't intend in taking 30 days to buy the phone but at least a little more than 24 hours...

My pixel 2's battery is getting drained rapidly after the Feb update, I tried resetting the phone and booting into Safe mode but those doesn't seem to work. After checking online, I found that several Pixel 2 users are reporting the same and even Google is investigating and trying to fix the battery drain issue..
Since the march update is released, Does anyone find the issue solved???
Just installed the update last night, have not messed with the phone since then. I was having issues with the Feb update as well. So far, with minimal use this morning, it is looking good.
I feel for you lot who had battery drain after the last update. My phone battery life literally has got better this last month. This was yesterday...
Mine started drinking from 100,% to zero overnight after the Feb update.
I've completely installed March's update only installing a few apps per day to make sure it's not a rouge app.
All good so far. Only losing 3% overnight (8 hours)

That's still a lot. I'm leaving WiFi on and it's only draining 1%. Maybe a full reset might help. But yeah, going slow on app installation is better for now.
Have just installed the march update. So far 15% drain with an hour and 15 minutes SOT. Definitely better than Feb, but not as good as Jan

I've not seen it < 2% since the Nexus 4 so i'm relatively happy with 3% in 8 hours.
I always say if I can get through the day from charge to charge then I'm happy.
If i travel and i'm using it more then I have a power bank.
The full discharge overnight was concerning but if I install the rest of my apps and its still at 3% then i'm going to stop messing with it and forget about it.
working much better
Just received my watch 2 as a gift from my cousin.
I'm not able to pass a day, like i read in the forum.
Out of charge at 8.00 am, i can't barely reach 22 (if i'm lucky)
just checked everything on the forum, tried an hard reset.
Battery fault?
I had mine since November, if I don't use it to track sports with GPS or constant Fit tracking I only need to charge at end of 2nd day.
If I'm using a lot of GPS / tracking it can be about 40 to 50% and I charge end of day 1 just so I don't have to worry about it.

Hello everyone
I just bought my first pixel it's a pixel 1 32GB
I'm upgrading from a Nexus 6 32GB
I love my Nexus 6 but after changing the battery once it was time to upgrade
What I wanted was some advice from people who've used this phone
I'm thinking of going right to the Android Q beta
But I do want to root the phone
I would also like to transfer most of my data over before I sell the Nexus 6
Thanks for the warm welcome in advance
Hello mate, the Q beta is usuable now but the new scoped storage can be make some apps misbehave when using the storage permissions. TWRP recovery can be booted or flashed, check the thread for install instructions or just fastboot boot it when needed.
For root use magisk, not sure if its working on Q beta 6 but check the magisk threads for details on that. Last thing, once you've unlocked the bootloader leave oem unlock unlocked and never relock the bootloader unless you are 100% full stock or you'll end up bricked (plenty of threads on this)
Hope that some help
I am use to using the Nexus tool kit what is alternative for a pixel
1. No need to go for Android Q right as it is still in beta.
2. You could follow guide from google on phone switch: https://support.google.com/android/answer/6193424?hl=en
Hope you enjoy your new phone!
I also got OG Pixel about a week ago. I jumped right into beta 5 and it was amazing. I was getting about 5 hours SOT. Now i am on beta 6. I upgraded as soon as it was available. I got MASSIVE battery drain. Google app was draining battery but i disabled it. Still i got about 3:40 SOT twice. Overnight on Beta 6 i am losing 6-8% when on Beta 5 i was losing 1-2%. Right now i reseted my OG Pixel and will test if it's fixed.
Thanks guys the Phone was shipped From Windsor today should reach my Home with in the next 10 days
Looking forward to Change from my Nexus 6 (best phone I ever owned ) but she's old slow now
Update Phone Came today at 8:30 AM I charged it and install My Apps and Android Q Beta
I am getting around 3 Hours on the Battery is this Normal ?
3 hours isn't unexpected for an OG Pixel with the original battery. They're 3 years old. They're still fine phones, but an $80 trip to ubreakifix might be in order. Batteries are only good for a couple of years. Planned obsolescence since they stopped putting user replaceable batteries in phones. Oddly, lots of people buy into the thin (hard to hold), no bezel (no drop protection and hard to hold), no audio jack (no real reason why not), no SD card (why let the user pay $30, when they can charge $100 for the same?), expensive (bragging rights) phones with a 2 year lifetime. Go figure.

3 Hours doing what? I noticed that when on LTE it drains battery on beta 6 even when you do not use mobile data and signal is strong. My nexus 5 does not do this. I hope they will fix this in final release.
I get around 4:30-5:00 SOT using LTE and manually switching to 2g when i do not need mobile data. WiFi about 40-50 minute gaming (on the way to work and back daily), youtube, browsing and messenger lite.
I also noticed that it drains battery overnight too much. About 5%. Still my nexus 5 on andorid 9 loses only 2% overnight and it has much worse battery (4 years old) and smaller capacity (2300 original but now i think no more then 1900 mah).
For example my Pixel is 2 years and 1 month old it was manufactured on 12 july 2017. Check your serial number in about phone -> model and hardware. First 2 letters show where was your device manufactured. Third digit is year 6 -> 2016 7->2017. Next digit is month 5-may, 6-june, next LETTER is day in english alphabet B->2. That's it.

Thanks for all the help this why I love XDA
Hay XDA Still rocking the Pixel but wounder if time update the rom
I'm still using Android 10 Build QP1A.191005.07.A3

Bit of slate reply but just go custom or flash GSI. I've just got a really blue OG pixel, needs a new battery but once that is done I'll be going custom/GSI route to exte d its life span.
