Do I have to clear cache and battery stats?

[Nexus One Android Development] irishrally:
You are fine. The control kernel is not a over-clocked kernel.
[Nexus One Android Development] wind0zer:
For best results, yes.
[Nexus One Android Development] Worsty:
Thought so myself but thank you for the clarification.

From the initial looks of it, the kernel i'm using is pretty awesome on the batt's life.
[Nexus One Android Development] irishrally:
We should get some people to take one for the team and let their phone do nothing all day. The easiest way to maintain a consistent phone usage among testers may be to have everyone do nothing and not use their phone at all (leave it home all day).

Maybe one day out of the week for each kernel could be a leave it at home today, zero usage.
[Nexus One Android Development] Worsty:
As i'm home studying for my paper today and tomorrow, i'll be glad to take one for the team. Just let me know the perimeters in which to follow.

For example, do i enable wi-fi?gps?3g? Any push notifications on?

Edit :

I'm just leaving wi-fi,gps,3g and multiple apps like Google Finance,seesmic,fring,gmail on and not going to fiddle with it for the rest of the day. Will note down my observations.
[Nexus One Android Development] persiansown:
You flashed the control right? (just making sure)
[Nexus One Android Development] irishrally:
Well that was a hint.
[Nexus One Android Development] Worsty:
Yup. Flashed the control.
[Nexus One Android Development] persiansown:
Not it wasn't, I sent everyone two files. The file everyone was supposed to flash now is the control.
[Nexus One Android Development] irishrally:
hint = sounded like you were surprised to hear the battery was awesome, so asked to make sure he was using the control, probably the kernel without more stock like voltages.
[Nexus One Android Development] persiansown:
The control is just that, a control. No variables.

[Nexus One Android Development] Casao:
Idle battery usage doesn't mean much to anyone though - I care only the slightest bit how much my phone eats when sitting idle, because if I'm not using it for a long time I can easily turn off the phone to save battery if I'm worried. And nobody else's idle usage will be useful for me, as my phone has different settings than anyone else's, so if your phone can do 48 hours idle, mine might only do 24. Don't forget that a lot of people have idle underclocks, which also changes things for people who don't/do underclock.

Normal usage is, by far, the best available way to determine this. There's no way to do this definitively without a script that will monitor everything automatically and compare, so this is second best.

BTW, I plan on taking a screenshot of my Battery Use screen at the end of every day, and I encourage others to do the same - this will also show a breakdown and exact time unplugged.

So far, my phone is still draining battery at a decent clip while active/listening to music, but idle usage seems to be down a bit. This is on control, obviously.
[Nexus One Android Development] RinTinTigger:
This is so untrue!

I CARE about idle battery consumption. The less the battery gets sucked in idle, the mor you have left over for POWER Usage ^^

And that power usage is taking up voltage should be clear ^^
[Nexus One Android Development] Nighthound:
I just entered my data from the first day's feedback.

Besides noting down the battery remaining, I also jotted down the usage (time and battery % used) for:

- display

- voice calls

- cell standby

- phone idle

Not sure if those stats will be of any use, but it may be useful to explain anomalies in my day to day results (eg. if one of the days I spend 1 hour more on the phone compared to my normal usage).
[Nexus One Android Development] mgorman:
never mind.

[Nexus One Android Development] Daswolven:
Having significant battery life issues with this kernel. I have had my phone unplugged for fifteen minutes, and I'm already at 82%, with 112% going to display! I never had this issue on TheOfficial, reverting back now until #teamDouche gets their act together.

Sorry. Couldn't resist.....
[Nexus One Android Development] persiansown:
is that a joke or not? Also thats the whole point of a control. To set up a base to compare everything against it.
[Nexus One Android Development] big nu:
huh?

@Daswolven

Dude this is an experiment.. your supposed to "detail" the specifics on how the "control" kernel.zip you flash worked with you as far as usage and consumption.. And all you did was rant..:rolleyes: tisk-tisk Daswolven.

This dev is trying to do something great and productive for the community..

Im about to give a write up on my report.
[Nexus One Android Development] Casao:
Meant to post this a while ago, whoops.

I'd call it light usage - Twitter/Facebook set to 30 minutes, maybe an hour and a half of music in bTunes, 20 minutes of streaming via thumbPlay, 30 minutes of browsing RSS. Most of the day spent sitting on my desk.
[Nexus One Android Development] Daswolven:
Yeah, it was. Sorry. I see way too many vague complaints about battery life in every thread, and took advantage of the lack of it here.

Was not a serious post. Will be posting my results before bed. :) Excited about this whole deal.
[Nexus One Android Development] persiansown:
Ah sorry. Should have realized. :)
[Nexus One Android Development] Nighthound:
The first time I read your post I was totally perplexed, until I saw your explanation a few posts down. When I re-read it, now it seems hilarious. Might save some people grief if you've added a smiley to the end of your first post =p
[Nexus One Android Development] Daswolven:
usually if someone can tell that I'm joking, it no longer amuses me.
[Nexus One Android Development] xCALLmeKING:
The control kernel definitely ate up my battery, however I feel that I had some heavy use with it.
[Nexus One Android Development] wind0zer:
How I recorded my stats from ABOUT

======= DAY 1 ============

Time since reboot - 30 hrs

Remaining - 14%

Display - 39%, cell standby - 18%, idle - 16%, wifi - 9%, voicecalls - 7%, system - 5%, OS - 4%, akmd - 2%

======== DAY 2 =========

** I obtained from spareparts coz i plugged phone to pc to transfer a ringtone, also I had restarted the phone at the beginning after kernel flash & charging. It should have been Time since unplugged instead

* Basically I noted down all things in About > Battery use.

Note to self: I'll reboot the phone after charge to avoid (timing) confusion in case I connect to PC during the day.

Hope this helps anybody wondering how to get around this and thanks Casao for posting the screenshot : )
[Nexus One Android Development] immiMIK:
DAY 2:

No battery loss standby mode for 1. 5 hrs, really impressed.

Down to 70% more than 10hrs see attached pic.
[Nexus One Android Development] big nu:
feedback

This was written @9:00pm 5/4

Last night before i went to bed i flashed the control.zip woke up to a full charge.

@4:30am I unplugged the charger with a 100% charge

CPU set at stock speeds 998/245

Active-sync running

auto-brightness on

No bluetooth/wi-fi

No LWP

Radio: 4.03. Xxx

*

@work downloaded a couple of files one was 20mb and the other was @ 1mb

I flashed them. I also did my normal web searching and fb/twitter check-ins, i also installed and experimented with a few apks from the market. I watched a short video or two.. all at work..

I left work at 1:30pm with 41%

Used gps for about 10 mins, more web.

I also find it harder to maintain full H data connection at times it'll stay at 3g and not connect..

@ 7: 00pm battery died so 14.5 hrs total w/ noted details
[Nexus One Android Development] Casao:
Anyone else on the control noticing extremely bad battery from local music? 93 minutes unplugged, listening to music via headphones for ~45 of that, dropped my battery to 85% remaining - 15% in an hour and a half, which is pretty inconsistent with how it was on stock. Was it just bTunes doing something weird? Anyone used bTunes/stock and compared?
[Nexus One Android Development] Casao:
What the **** are you doing with it to get battery life this? You're on the control, right? Do you have any background sync things turned on? This is ridiculous, and I'm not even sure what could be giving you battery life like this beside not actually using your phone.
[Nexus One Android Development] immiMIK:
Yes on control, sync is on, I'am using Juicedefender for managing APN and Wifi and of course SetCPU.

The phone was idle for around 5 hrs in the above pics :p
[Nexus One Android Development] iammuze:
a future study could be done with a tracker app that needed to be installed

it could track uptime, charging and battery status, and log it in a handy timestamped manner.

maybe bundle the apk in with the update.zip for the control kernel

we could expand and let the app and survey track signal strength too. if the app is bundled with the control kernel, it could keep data between kernels in a cache and even calculate differences between them.

these all sound like things android (or at least other apps) already do, so...

just a thought. unfortunately i'm not a dev, so i can't pull that off.
[Nexus One Android Development] DDM123:
I'm a little late to the party, but I figure this would be a more effective way of getting more accurate results, and more of them:

Wipe battery stats and flash, charge to 100%, let the phone idle for an hour or two. Use the web for 20 mins, play YouTube and/or music for 20 mins, play a game for 20 mins, whatever. Record battery % remaining, and repeat.

As long as the users are consistent, this seems like the best and quickest way of getting results. Also eliminates the variable of radio tower proximity as long as the phone stays put. The differences might be small enough so that using a kernel for a day would be inconsistent, since a long phone call might be enough to make a more battery-friendly kernel seem like it's using more power than a worse one.
[Nexus One Android Development] Casao:
That's why you do it for multiple days, trying to hit the same days where possible. That's essentially a synthetic benchmark with very little bearing on the real world.
[Nexus One Android Development] Daswolven:
Going to be spending tomorrow in a very poor reception area for most of the day, Friday as well. (county jail actually) I always get horrific drain on those days, so I'm considering using 2G only for two days in the next cycle to try to balance it out. I wont have any jail time then. I live in a Tmo dead zone, 20 minutes from work I'm bouncing off AT&T towers unless I tie into my WiFi, so I'm thinking this might even out. Also thinking this might not be necessary. hmmmm:confused:

(can't Post links so remove the space)

We should get more people to use monitoring programs like that for this test. I think you can adjust for personal usage fluctuations.

I would post my battery stats but I can't because my phone died :/. I tried to make it last until I could get to a computer with the android SDK on it so I could take pictures, and none of my usual screenshot apps were working. Unfortunately I didn't make it. The damn Engineering lab is a faraday cage... My phone dies trying to get a signal.

I posted more detailed info in the spreadsheet...
[Nexus One Android Development] soundwave9999:
Not Bad...

kernel seems to be working better each day. 2nd day gave me 6+ hours than the first day. even though today i had LWP running the whole day and twitter for android animation on it still gave me 17+ hrs with 14% left. my usage is moderate to heavy>> 104 txt, youtube, web, music, email, twitter, games and a few phone calls. i dont use wifi and brightness is at 0-25%. the first picture u see battery percentage was at 96% since unplugged. so to finish things off i discharged @ 7:15am and charged again @ 1:35am. IMO i think its doing pretty good.
[Nexus One Android Development] theloginwithnoname:
Did I miss the name of that app in a previous post of the thread? If not, interested in it - what's the name and where can I get it from, if not the market?
[Nexus One Android Development] DDM123:
Not really, but that's fine I guess.
[Nexus One Android Development] swgbex:
I don't know of it has been mentioned beore but search for "systempanel" in the market. Its free.. just remember to enable the monitoring if you want those pretty graphs.
[Nexus One Android Development] Casao:
No, that's exactly what it is - it's not real world use. You alleviate the issues of "Someone made a call and it screwed up their battery life" by trying it for multiple days and having as many people as possible doing it.
[Nexus One Android Development] Daswolven:
I agree. A study like this over multiple users for an extended period eliminates the variables by looking at an overall picture. It's well worth the effort.
[Nexus One Android Development] DDM123:
How many people are in this thing? If it's more than 100 then I guess there's a decent enough sample. However, there won't be quantifiable data to back it up as in, "I used XmA with this particular kernel during this time frame. Therefore Some Kernel is better than Some Other Kernel."

I'd rather this be based on numbers, even if those numbers are linked to a slightly inaccurate battery gauge. At least they'd be consistent and less subject to user habits and you wouldn't get subjective experiences such as, "well, my battery FELT better with this kernel than the others."

With a massive sample, your logic holds true but I'm pretty sure that this experiment isn't on a huge scale. It's nice to know X Kernel is better than Y kernel, but by how much?

That being said, I support all of these endeavors and I'm very curious which proves to be the better kernel, and I'm grateful. I'm not being grumpy here, I swear.
[Nexus One Android Development] liam.lah:
If people put how long the battery lasted, from time off charge to time to charge or run out, post their usage stats, and any other notes, i think we can get a fairly decent idea of how the kernels are doing.
[Nexus One Android Development] hah2110:
When will the results be released?
[Nexus One Android Development] jblazea50:

akmd?

Anyone know what akmd is¿ :confused:
[Nexus One Android Development] persiansown:

Just a reminder, tomorrow is the first day everyone is supposed to switch to the testing kernels from the controls :)
[Nexus One Android Development] swgbex:
I'm getting stuck at boot (loop), I reflashed the control and I'm able to boot again. I don't have to wipe or do I? I've used UV kernels before, but perhaps this one is too aggressive.
[Nexus One Android Development] Daswolven:
Much appreciated. On test today, looking good so far.

I didn't do much yesterday, but I got nearly 7 hours and it only took me down to 79%, which is great. A lot of that was idling, however.

Today isn't quite as good, but it's getting more use too, so who knows.

Either way, so far test appears better than control, but I don't have a lot of basis to compare with.

[Nexus One Android Development] Nighthound:
Hi guys, I think there are multiple versions of the test kernel going around? So there's not much point discussing whether you're getting better performance on the control or test kernel, at least until kmobs sorts out the results. :)
[Nexus One Android Development] persiansown:
Last day, please make sure to post your results :)
[Nexus One Android Development] eboy44:
Control:

day 1- 13hrs unplugged. 62% battery. light use

day 2-13 hours unplugged moderate use. 55% battery

day 3- 12 hours unplugged, 15 min internet use, 30%

Day4- 13 hours use. 28% battery. moderate use

day 5- 14 hour use light use, 40% battery

Test:

day 1- 13 hours unplugged, slightly more than moderate use, 32%

Day 2- 13 heavy use 18 % left

Day 3- 6 hours moderate use - phone DEAD

Day 4- 8 hours moderate use phone dead

Day 5- 3 hours use, 30 min GPS, phone at 20% phone died after another hour, recharged and phone died once again in 6 hours

No, the reason that it is free, is because all the maps are stored online and not downloaded to your device. If you want maps stored on your device, you will have to pay for a commercial GPS app.
