what effects the gps? - EVO 4G Q&A, Help & Troubleshooting

I've been messing with my gps lately and noticied my gps jumps from 1500 meters to 1 meter. Before my backup was erased it was so accurate it would show my exact position in my house. How can i get it back to original?

signal strength percentage

I would like to only replace the signal bars with a percentage meter. Any quick replacements for this?

[Q] Battery meter

Is it just me or is there no battery meter on the lock screen that indicates what percent the battery is charging when the phone is plugged in? I remember seeing one on my first Incredible, but it seems that with the new Sense on the I2, the meter is gone.
Is there a way to get it back?

get this its amazing. so customizable.
Thanks, but I'm looking for a way to have it show up on the lock screen. I'm not sure why this new version of Sense doesn't have it.
I use the circular battery indicator which displays the current battery % in your notification bar; it can be seen from the lock screen.
I find it accurate and more informative than the standard battery indicator.
No battery threads for the I2? Can you comment on battery life? About how long are you getting on a normal usage cycle. 8 hours, 12 hours, 24 hours? Are you configured for max battery life?
I've been using the Lightwell live wallpaper, which shows the battery level quite large on the lock screen as well as on all the home screens. I get more use out of it on the lock screen though. Lightwell is a really light weight live wallpaper, does not eat batteries.

I am a really heavy user, especially on my work days. I have developed the habit with my old device (Eris) to have it on the charger at home and at the office. I will say the Eris would not come close to surviving a full work day, whereas I'm fairly confident the I2 would.
My commute alone consumes around 20% battery each way (40% round trip), with each way lasting 40-60 minutes (80 to 120 minutes round trip) depending on traffic. The usage during this time involves media playback (music or podcast), maps (uses GPS and 3G radio), and bluetooth (how I play through my car stereo). I don't like having a tangle of wires in my car so this is without car charging and audio cable. This leaves me with 50-60% to survive the rest of the day if I don't plug it in.
On my off days, I don't have all of this going on for long periods of time. I've survived an off day completely untethered to power without going below 50%.
As always, your mileage may vary. I live in an area where coverage is good so network bouncing isn't that big of a problem (this can eat batteries). I also generally use apps with lightweight services (background processes), which can be a pain to find and you don't always end up with apps with all of the features you want this way.

[INFO] Sudden battery drain with marginal or no mobile signal

Hi
This has happened a few times now when my phone is in a place with barely and quite often no mobile signal, always the same place, same building that is in a bit of black spot. On coming back to the phone after an hour or so I've lost 40-50% of battery power, and of course the phone is warm because of the more rapid drain of power. It is the warm phone that alerts me that I've probably had a massive battery drain event again, turning on the phone shows no service, the service comes back fine as I walk away from the building. This rapid drain event never happens elsewhere, but then normally I'm getting a decent signal everywhere else.
The battery chart shows the drain clearly, and as soon as the phone is back in a decent signal area the drain immediately stops and is back to normal battery usage apart from having lost half of its power.
The battery usage shows the phone was hardly sleeping for the duration of time in the low/no signal area, presumably kept awake by the radio chip constantly reporting no signal or something like that.
I'm using the stock ROM in Europe on Vodafone, software version 1.29.401.11.
Surely it isn't normal for the radio chip to cause so much battery drain in a no/low signal area, where is it trying to reach for a signal, Mars? :cyclops: My other smart phones same carrier in the same place with the same no signal situation were absolutely fine and didn't do this.
Interestingly the cell power usage percentage doesn't increase for this problem, so while the cell power usage is half the battery when this event occurs, this doesn't register in the cell power usage percentage, or anywhere else for that matter, just the overall chart takes a dive down.
Perhaps this issue explains variable battery life some are experiencing if they are in or travel through areas of poor or no mobile signal. Something isn't quite right with the way the radio is dealing with this situation, hopefully fixed in the next update.
Regards
Phil
Same thing is happening with my 1X. I'm working in such a building too for the last couple of weeks, it's very annoying.
I'm also on Vodafone from the Netherlands
Sent from the HTC HD2
On Vodafone in the UK and also get bad drain when signal is poor. Signal does affect battery drain though.
Same when the phone is resting in a low wifi signal with wifi on: massive battery drain in that case. Extremely annoying!
Hi
I've updated my One X with the newest RUU that contains the latest radio 2.120, this is a stock ROM for European unbranded phones and installs without needing a rooted phone.
This radio was pushed to some places in Europe last week I believe but we haven't had it in the UK.
I'll see how it goes, but it is very annoying and certainly not right for a low/no signal to drain the phone so quickly.
Regards
Phil

[Q] Battery drain with no wakelock

So I've been having battery drain issues. I tracked down one wakelock due to the exchange services, and solved that problem. However according to BBS my phone is in deep sleep for >95% of the time, yet I still have a 200-350 mA draw. GPS/Wifi off, and all location services have been turned off.
A restart solves the problem temporarily however it comes back the next day. Signal strength where I'm at is rather poor, about -110 dB or 29 asu usually. This heavy of a draw seems to be a bit much, even if the signal is weak.
Any suggestions on what to look for?

I am having similar problems at night.. all fine during the day, but draining at night. Neither better battery stats or wakelock detector seem to be offering a clue...

[Q] battery problems?

Hello.
I'm using nexus 7 2013 lte for a couple of weeks and i experience some troubles that quite bother me. Device is running android 4.4.2 installed OTA.
First of all, battery drain in sleep mode is kind of unpredictable. At night (8-9 hours to be exact) device can consume 3%, 5%, 15 or even 20. My first thought was to check installed third-party apps which could cause it. But i didn't manage to find the reason of the problem, the statistics of battery looks OK, tablet can work fine for a couple of days, and then same thing occurs. I found no dependance to 3g and wifi on/off: there can be 3% for night when device is just left with wireless connections, and there can be 10-15% with airplane mode on and precursory reboot. Battery drain happens only in sleep mode, and battery times are absolutely normal on heavy tasks (10 hours of 720p video, 3:45 of gaming). The other device I use works just fine with same apps installed, same settings and cellular carrier: consumption on idle is low and constant.
Some weird jumps in battery level also can be noticed: from current level to 100% and back on: example 1
example 2
No chargers or usb were connected, temperature around was constant. Can't find any reasonable explanation to these jumps.
So should I suspect that my item has any hardware faults of battery, or there can be some software issues?
And another minor question: how good should be wifi reception on nexus? The "other device" I mentioned above (which is galaxy note 2) has solid, good level and speed of connection, while nexus seems quite worse on this subject. For example, in the room where I am at the moment, note has 3/4 bars in wifi symbol and fine, constant speed, and nexus has 1 or 2 bars of 4, and connection looks pretty laggy.
Thanks in advance for any response.
Try factory resetting and testing sleep mode battery consumption again without installing/touching anything. If its a hardware problem, it will happen again. Wifi reception should be the same or better then note normally, but as i said, factory reset and try, if the problem(s) persist, its a hardware problem.
Those battery graph peaks were still present last night.
I've just performed factory reset, will see if it changes behavior of my device.
Thanks!
So, after factory reset on pure system without any non-stock apps I got these results:
Battery consumption on idle was usually between 1 and 1.5% per hour. There was a little of instability (marked red on the screenshot), but just a little. Nothing like sudden 15% per hour that used to happen before. Is 1.5% good enough for sleep mode on stock firmware with 3g(not lte, 3g) and wifi turned on?
No jumps to 100% were noticed during these 24 hours, but they didn't happen every day. They worried me most, so I'll continue to check if they occur again. Hope they disappeared after factory reset.
As for the next step, I gonna install my usual apps and see if it affects battery perfomance.
By the way, about wifi reception: it still had 1-2 bars where galaxy note has 3-4. But then I ran some speedtests, and connection speed on nexus was usually significantly faster then note's. So wifi works just fine, it is just a matter of wifi icon calibration.
For a bit my batt life was suffering. I found it worked to turn it off, charge it fully, and then turn it on again. I actually wanted to know if there r any good task killers for it?
