Method 3: Factory reset

In case you have tried all the above methods but still there is no change in the performance of your battery, it is best to perform a factory reset that is more advanced than wiping cache partition which erases everything including all applications. Here is how to do it:

Go to Settings >Backup and Reset >Factory Data Reset and Reset Device. That’s it. But do not forget to create back up of the device first as this process will erase everything from your handset.

This will fix up the issue most certainly but in case the situation is still same, it is suggested to replace the battery to solve the issue.

  1. In the past when I got the Nexus 7 did the wipe the reboot would take a few minutes and you could see it loading. Now when I wipe it takes like 3 seconds to go to reboot and it’s charging fine Just draining fast like I love you more Only I’m draining faster

  2. My Nexus 7 has started to charge very slowly and will no longer get to 100%. This only started happening after I did a factory reset to fix a Bluetooth issue
    Tried all the steps and even a new battery.
    What can have happened?? Anyone got a fix??

  3. Faulty USB connector fixed by squeezing the socket together in both directions to get a good fit with male connector. Also placed a very fine soldering iron tip on each of the five pins. My Nexus 7 2013 is now back to new. While you have got the back off reseat the two main connectors and place brown tape on cable to stop movement. Also place foam above connectors to keep pressure on. The connectors are involved with touch screen.
    Note: Disconnect battery while you do this work.

  4. This will work only when the charging issue is related only with battery drain. This won’t work for many people. I made this earlier and nothing has changed. After that I bought a USB current meter and it showed me that my Nexus 7 is charging with only 0.44Ah. I’m using the original charger and cable. After that I measured if the charger is corrupt but it’s ok. So I changed the charging port of my tablet. After that everything work fine. So if your Nexus is charging very slow but your battery last for long then your charging port is corrupted.

  5. I had this same problem. I used to have to take off the back cover and unplug the battery for serveral hours then plug it back in, and plug in the usb cable and leave it turned off for it to charge back up. But then it started again. I just tried the clear cache from recovery, hope that serves as a better fix. I can’t seem to get more than 650 ma charging current though.

  6. Hi, Ever since my system got updated to v5.1.1, I have been experiencing touch issues, like : typing the letter i, once and getting it 3 or 4 times repeatedly. Sometimes while browsing, the system goes wild and changes from one screen face to another without any prompting.If i shut down with the power button and reopen the screen, it stabilizes for a while…….maybe 5 to10 minutes and starts again. How do i solve this? I have a 2013 nexus 7. When new i never had this problem at all. This tablet was so much fun, now its a big pain.

  7. I had the same thing, but this worked for me…I killed/stopped all the
    apps, then I took the back cover off, disconnected the battery and
    reconnected it. Now the Nexus charges to 100%. Not sure if it was the
    battery process or stopping one of the intensive apps, like Facebook
    and/or Messenger, but one of the two fixed the problem that I was having
    for months.

  8. i have the same problem as Stefan, got stucked at “no comment” level and after almost 2 minutes the tablet got restarted and the android came up withou me doing anything . but no recovery, no cash clearing!

  9. The steps were easy enough to follow, even though I had to it twice to get to the recovery menu. But the steps completed as shown in the instructions.
    I performed these steps at around 3am; the Nexus battery power registered at 55%. I put it on the charger and saw the battery power increase to 57% within minutes!
    Upon waking up at 8am, the Nexus’ battery power registered at 35% charging, connected to the charger. Its now ~1:30pm, and the battery power is now 17%, with the “connect to charger” message (I never removed it from the charger or moved the device since 3am).
    I do appreciate Chevy Powell from How To for the easy to follow instructions, but I have to say these steps did not resolve the #nexusForeverCharge problem for me.
    I hope that @corycrew:disqus and others who were seeking a detailed experience find my comments useful.
    Hope it works for you.

    1. That sounds like the issue with yours might be the port itself. I had the same issue with my phone and had to send it in to get a replacement.

  11. I have solved poor charging and
    quick discharging of my nexus 7 by the following procedure:

    1) install Battery doctor (free on Play
    Store)

    2) disable automatic updates for all
    apps (on Play Store)

    3) uninstall all rarely or not at all
    usable apps

    Thats all! Wish you all with same
    problems good luck

  13. This “fix” didn’t work for me. So far the only thing that has improved the charging rate for me is connecting/disconnecting the USB cable several times. Went from ~125 mA to ~800 mA current. (I use Galaxy Charging Current Lite to monitor the charging rate.) Weird, I know… don’t ask why/how. Feels like making rabbit ears out of clothes hangers and aluminum foil. Definitely need a fix to this issue, Google!

    1. I had the same problem. Found out there was some sort of corrosive buildup on the usb port. Every month or two I have to scrub it with a toothbrush moistened with WD-40. Seems to do the trick. Your connecting/disconnecting procedure is probably scratching through the buildup in a similar way.

      1. Thanks ercdeck! This worked for me (sjquicksilver’s connecting/disconnecting the USB cable sort of gets things going but none of the other ideas (and there are many!) worked).
        I would recommend methylated spirits – NOT wd40.
        WD40 will probably leave a small non-conductive layer (think oil) when the rest evaporates…

  15. Confirmed working. It’s not massively fast like it used to be but I suppose that’s the result of heavy and long usage over the years. But it’s working.
