IPhone :: 4 On DFU Mode And NO POWER?
Mar 28, 2012
I was syncing my iPhone 4 to my PC and it restarted with black screen and went into recovery mode, however, when I tried to restore it the screen went white and so I pressed the HOME + POWER at the same time and it went all the way to black screen. Now, it says the iPhone is on DFU mode and whenever I try to restore it, I am getting an error on iTunes. I would like to know what are my other options to power ON my iPhone so I can go to recovery mode?
Info:
iPhone 4, iOS 5.1

I've searched and am struggling to find much on these. What do they do, and how are they different?
According to HTC: Note: IfData connection is selected, HTC One automatically disconnects from the mobile network after 15 minutes when the screen is off and the data connection is idle (no download activity, streaming, or data usage). It reconnects and then disconnects periodically when the data connection is idle to save battery power.
Do these affect mobile data, Wifi, or both? Do they affect anything else?
I've left these off because I don't know how they work, and am getting fairly short battery life (10 to 15 hours, depending on use).

So I am having a very strange problem. I have been using the Situations App (formerly Nokia Situations) to automatically put my phone into offline mode, and power saving mode over night. 9pm to 6:30am.Recently the phone as started refusing to leave the offline mode in the morning. Even if I try to change the profile manually it says "Unable to change profile". The only way I can get out of offline mode is to reboot.I uninstalled Situations, and manually put the phone into offline mode and power saving mode. By the morning I had the same issue, stuck in offline mode until reboot. So it's not the App causing the problem. I've tried a soft reset, same problem still.
I also noticed that over-night (from fully charged before 9pm) to 6:30am I used about 70% of my charge. (A combination of power saving mode and offline mode is killing my battery!)I would have to go to work and immediately put my phone on charge! I.e.. 12 hours of offline + power save has drained my battery almost completely.Last night I decided to use the Situations App to put the phone into offline mode, BUT NOT activate power save mode.This morning the phone had virtually full charge and it had no problem returning to online mode.So it's ONLY if I use BOTH power-save and offline. (Tonight I will try using power-saving mode and NOT offline mode to see if it's only the power-saving mode causing the issue!)If I manually enter offline+power-save mode, and then try to return to on-line/non-power-save mode, relatively quickly, i.e.. Not over-night, everything is fine. It's only over night the problems start!

Just updated two days ago and my Airplane Mode icon will take me to the settings screen where I have to tap on Airplane Mode again which turns it into a two step process and makes the icon pointless. The other thing is that the screen is not dimming like it did in Power Saver mode. I keep my screen about 1/3 because indoors it's all I need and it would drop it about 10% before I updated to 4.3. Now it keeps it at the 1/3 default no matter what. I can't really say whether it's having a dramatic effect on battery life, but it would be nice to get that extra 5% in times of need.

My phone battery is dead in 10 hours or less. I think the problem is it does not go into a power saving mode (sleep mode?). I have rebooted, restored (twice), let the battery run out and restart several times to no avail.

What's the difference and if I have both on does it cancel out the other? I had both on before and my phone never turned off the data connection.

I bought yesterday a Nokia X2-00 and been exploring it for a while, so far so good, pretty happy and satisfied with it, but there's a problem that bothers and I can't seem to find a solution for it. About the screen-saver, I can, for example, put it as a digital clock, and set a timer for when the phone to switch to screen-saver mode. Problem is, I don't seem to find anywhere an option to play with the sleep mode - no matter what, about 10 seconds after the screen saver goes active, the screen goes totally black (goes into sleep mode) and I need to press a button to wake it up. No digital clock display, no nothing.I need to be able to see the clock (and possibly an icon for missed calls/new texts) without having to touch a button. On all my old phones you could play with both screen saver/power saving/sleep mode options, but not here. What can I do?

Since I bought the phone I have had power saving mode enabled. When it comes to paying games like need for speed, what am I missing out on with power saving mode enabled? It seems to be running fine with it enabled.

At first I though this was because I froze too much with TB but now when I've unfrozen everything it still doesn't work.
So far I've found "EmergencyManagerService" is related. I started trying one by one and found this one but then unfroze all.
I get a pop-up saying to wait while it configures (0/100)... But it doesn't ever turn on.

Today, I turned on my extreme power saver mode. I turned it on at 1 p.m at about 11% and at 3 o'clock it was down to 4% . That doesn't really seem like any kind of power saving to me. I burned up 7 percent in 2 hours, and I wasnt using the phone. I think I might've used less power had I not done anything!!

I just got my S6 after having an S5 and I don't know if this is the same for everyone but I wanted to ask.
I used to be able to get 12 days out of my phone on UPS on s5 but the s6 only goes for 3.5 days?

Although I have it so power saving mode doesn't officially 'click on' until battery is at 20%, should I be leaving the icon on at all times? I guess what I'm confused on is, does it really enable as soon as I click power saving or does it basically say it's ready to go, not on, but will click on at 20%?

I have noticed but just a few times. I will have my phone keypad locked and in my pocket. I will take it out and unlock it and it says Power Save Mode. Then when another key is pressed it goes away. What is this? Is it an automatic thing or am I pressing something to activate it?

How can I disable the power save mode in Nokia C2 01? I want the digital clock screen saver to appear all the time when I am not using the phone, but what currently happens is that few seconds after I stop using the keypad, the whole screen dims and the screensaver (having the digital clock) disappears as well.

In my Nokia C7 device, If I want to select dual or 3G in network mode, I have to deactivate power saving mode. In other words, when the power saving mode is active, only GSM mode will work and 3G/video calling will not work. If I deactivate power saving mode to make a video call, device starts heating up and power in battery decreases very fastly. How to keep power saving mode active in dual and 3g modes?

Lollipop 5.0.1 driven G3 are normal, or if there are fixes I am missing. I did switch over my SD card from my previous phone (Galaxy S4) and some things (music, photos, contacts) seem ok, while others aren't...
1) Cannot seem to update/install Apps - It just sits there acting like it is updating, the status bar scrolls, but nothing gets updated (or installed). As an example, I tried updating Facebook through the Google Play Store - My Apps option, sat for 10 minutes, and it never updated (but it still says I need an update). This is true for a large number of Apps that I have. I tried to install Helium so I could back up before a factory reset, and the same thing happened. It never installed.
2) Network vs. Wifi - At home, I use my Wifi connection, and I noticed that both the Wifi signal indicator and the Network Signal indicator display. I know this did not occur on the S4 (with Android. 4.4.4). Is this normal behavior for Lollipop to display both Wifi and Network connectivity?
3) Can't find a microphone for Speech-to-Text messaging on either the LG or Google keyboards. I saw one article that shows it is in the predictive text field area, but it isn't appearing on mine. - Actually - I just resolved this - it is hidden under the settings icon on the LG keyboard. I had to long press the icon for it to display.
4) No Silent Mode from the Long Press of the Power Button.

I cannot get my phone out of power mode. It is turned off, but auto brightness goes lowest possible still. No lights on buttons, no haptic feedback, no sounds (hate them, but turn on to see).
It's not hardware as the haptic buttons light and vibrate on boot... Just nothing after boot up. Haven't done anything but let my phone hit 10% battery before charging.
