Whenever I do the speed test with my phone, the highest score I've been able to get is 1.27 mbps, but on average its about .80. I live near chicago so I figured I'd get better speeds and I noticed many people are getting up to 5 mbps.
Is there a radio update I need or is this the phone, or is it the area? I test it when i'm outside with clear skies and it stills only shows that much.
I usually get great speeds. My maximum has been near 7 mbit/sec down., and my average is 3 mbit/s.
When I hold my phone tightly, the signal goes down, but I never lose a call or any bandwidth. Try putting the phone on a table.
When I had my G1 I was having crappy speeds (maximum 1.5 mbit/s down, average 0.8 mbit/s) compared to what T-Mobile is capable of. Your problems could be location. Maybe, just maybe, it's the device, but I highly doubt that.
have u try to installed Lagfix? just my 2 cents.
Yes I did. Its been great for the overall function on the phone, but hasn't really affected the date speed.
I got 12% battery drain in 17 hours, standby. I'm not a pro at android but I might give a little tut. on how to save battery life to the max. Atleast, it works for my P500 so it should work for you & for any other android device as well.
Uninstall every unnecessary app, including system apps (those apps, that does not mess up with the system stability - If you uninstall Email app, you will not solve your problems with Gmail app).. same with Messaging. That said, leave as minimum apps in the background as you can. App killer does not solve this problem, it just closes bg apps - they restart after some time. I'm using ATK (Advanced Task Killer), It usually kills 1 - 3 apps, so.. I have a minimum of apps running in the bg.
Basic stuff.. turn off your 3G, wifi, bg sync, gps when not in use. If you need to check your email, use 2G network only option, not 3G. Use 2G always when you don't need 3G speed. Screen brightness is not that important if you set it to anywhere below 70%. It should not drain the battery that fast.
Setcpu - profiles - governors--
My profiles are as follows
Charging - 480min - 748max
Battery <90% - 245min - 600max
Battery <70% - 245min - 600max (U can live with one profile for the battery, I have 2 in case I want to change the 2nd profile)
Screen off - 122min - 245max -- This is what saves my battery in standby.
The governors are ondemand for usage & conservative for screen off.
I'm using Void.echo rom with tapps & gapps modules, uninstalled everything I don't need.
I hope this helps If anyone has a better idea on how to save battery life, please share yours as well.
Thanks for your post, but actually most background apps don't drain battery. I have made lots of experiments (removing system aps, preventing autorun etc., and I don't see any major difference in battery life. So now, I'm on stock 2.2 and I'm now at 80% after almost 30h use: about 20 min talk, 10-15 min wi-fi (mail), 10-15 min EDGE. The latter by the way drains battery more than wi-fi. So instead of messing with system apps I recommend putting the phone in airplane mode during the night and as mentioned in the above post - not using 3G when not needed (EDGE has decent speed).
thats the why linux works !!! use all the memory u possibly can...These Microsoft *****es have changed the way computers were supposed to be used not reinstalling windows and other crapware all the time..Switch to Debian while its still time
And i use these settings
screen off 245-245 powersave (otherwise phone gets hot Its summer in india)
600-245 ondemand otherwise

If there are many apps running in the bg, phone runs out of ram, so it tries to free up some space constantly. I think that drains battery, not the apps themselves. As well as the more cpu power is used, the faster it drains battery. Airplane mode shuts off any connection, so either that or you could just shut down the phone during night. Hmm you could tell me how to prevent app autorun, i have not looked into that.
btw juicedefender does wonders with the phones battery i had a 2% percent over night normal mode (not airplane) no 3g/Edge/Wifi/Bluetooth active and just sleeping

True about windows & linux hehe. You havent tried 122-245mhz on screen off? Ofcouse, it lags even when i receive an sms, it's something like this - the screen turns on, then after 2 sec. i hear a notification, then after 1 sec. i see the sms but that does not make any problems for me, it's extreme powersaving
I don't get the point of airplane mode while you're sleeping.
If you don't want to get calls while sleeping, shouldn't it be better if you turn off the phone?
I had a good experience with JuiceDefender until now too. Last night my phone was 100% and no airplane mode while sleeping. It drained only 3%.

From what I've read, Android doesn't swap. It'll just kill the background apps on it's own. I don't think there even is a swap unless you root, rom and create one on your uSD.

It's more convenient, because the on/off process is quite slow...in contrast - airplane mode on/off is 3-4 secs. In airplane mode you can still use wi-fi. Last night the battery drained only 1%
i read somewhere that changing the CPU speed doesnt change the voltage, thus it does not affect battery life... anyone can confirm this???
As far as I can remember from school, a logic gate uses more power when switching, thus a higher frequency would also mean higher power drain (higher frequency = more switching of the logic gates), without voltage modification.
Voltage is changed in order to keep stability - higher voltage means a more stable logic signal, and a faster switching gate, and thus people reccomend using a higher voltage for higher frequencies/lower voltage for lower frequencies.
Thus, a CPU with so many logic gates does not operate just like a simple resistor. In fact it is worse, because when you use higher voltage AND higher frequency power drain is increased much more.
On the other hand, most modern CPU's simply deactivate CPU regions when idling, so, in case of our hardware (constant voltage) there should not be such a great difference when idling (most of the CPU is powered down). The only thing is for the phone to be REALLY idling (no background tasks eating too much of the CPU when screen off).
Basically, what this means is that if you want extreme power saving use a governor with 128MHz minimum and have as few background services as possible (or at least the ones that are there should be optimized for the least CPU usage).
Now I use the standard governor (248 - 600) and I thing my idle power drain is OK.
I guess I will test a governor that is plain 600MHz and one wit 320 or 480 as a minimum, in order to see if power drain is higher when using a lower lag configuration.
And, just as a guess, if background tasks are triggered by timers, a governor with just 600MHz (or 320 - 600 or 380 - 600?) could (just a wild guess) mean that background tasks take less time to execute, and leave the CPU to si more in IDLE mode, causing a very similar power drain as an extreme power saving governor. But this is just a guess, i have not tested it yet. And it also depends on what apps you have (what the apps do when phone is sleeping).
Basically, my best advice would be to watch the apps (after you install a new app, wait for a night to see if the new app causes a higher drain; if it does, search for another app that does the same thing)

I don't know about CPU's as much as u, but simple logical thinking helps here.. Low frequency + minimum of bg tasks = great power saving, I have now used the phone for 36hours without charge, 61% battery left. That is not only idling, i write about 50 to 150 sms a day & use the phone for other stuff too. So, those governors & frequencies i mentioned earlier in this post, helps a lot.
fransisco.franco thinks otherwise read the his post that contains the link to his rom devoid.francov6(ROM is cool btw and unfortunately i have a slow sdcard )
I think the first post is by far the best I have seen so far.

Wow, only 1% all night?
I'll take a deeper look at your tips!
I use devoid.franco with franco.kernel v12. From all ROMs I've isntalled, it's the best: great performance and long battery life.
I get 5% battery drain in 7:30 hours (at night), without doing anything special, without running a custom ROM and without uninstalling apps. I just make sure GPS, Bluetooth, WiFi and data are off before going to bed.
Hi,
today i used my SGS2 for comparing my cars instrument with gps-speed. While driving with cruise control i got 122,4 km/h (this is around 75mi/h). This value was very stable, after a minute or so there was 118,x for some seconds and then 122,4 again. No values in between . That looks very strange to me, anyone experienced the same effect? (using Lightning ROM 1.3, with both "GPS Test" and "Maps (-)")

Speeds as low-res steps
I'm having the same experience with mine and this behavior appeared suddenly. It doesn't matter what speed I'm going in or what app I'm using for measuring speed, they all show speeds in clearly divided steps with low granularity. In Locus Pro, the speed chart shows clear steps in recorded speed (I cannot post screenshot yet due to rookie status)
Both SpeedView and Ulysse Speedometer have the same behavior, though the jumps differ a bit. If I remember correctly some of the steps in Ulysse was (in km/h): 76, 80, 83, 86, 90, 94. Nothing between these.
Browsing through the recorded tracks in Locus I can point to the date this behavior started, but I have no idea what I did that day, unfortunately.
yesterday i've used runtastic, it works like expected, while the other two mentioned earlier still fail...

Hi,
This is also something I've noticed. Using GPS Test I've found the "resolution" of the reported speed from the GPS to be 1 m/s, which is equal to 3.6 km/h. This explains why some applications seem to have steps of 3-4 km/h on the speed rating.
Fixed somewhere between ke2 and kf3
I upgraded my phone to from ke2 to kf3 today and this issue seems to be fixed now. Otherwise, see this thread for a similar discussion.
Something to think about guys.
To start, let me tell you that my WiFi + bt speed is very reasonable, even at some distance from the router. My internet speed is 20mb.
Noticed yesterday that my WiFi went well below 1mb when paired with bt, and half my usual speed with bt off.Long story short, I realised that I changed CPU governor to userspace day before in System Tuner and forgot to change it back. Switching back to interactive brought my speeds back to where they were. While its not really useful info, I wonder why does CPU governor affecting WiFi speed with or without bt on.
Anyone?
Sent through the wormhole from my CoinInserted Sensation OG.
That is very interesting.. could just be a coincidence though.
I just switched to a newer TP, C2 serial and my wifi is a bit better but far from great. I do get those extremely weird spikes of extreme low and extreme high speed. I recently changed my router the a much higher end model (not high end but better, D-Link Dir 655 Xtreme) and it helped a bit but I still have a strange dead zone in my house that only affects the TP and no other devices. That and those moments were the speed decreases greatly.
I never could figure out what caused it. Could it be the governor adjusting itself on its own? Maybe related to Performance vs standard settings?.
