[Ascend Mate 7 Q&A, Help & Troubleshooting] harrywenjie:
Basiclly most huawei services can be disabled or uninstalled, what I kept is a shorter list, so I'll just post the list I kept. Whatever you don't see in this list is generally safe to remove with my own testing. Note, I have uninstalled the stock camera and stock gallery, and replaced with google camera and quickpic, and used sdfix (a must for kitkat 4.4) and picture2sd xposed module to make my camera save to my external sd card. These are user apps, so they are not in my list, this list is for system apps only, user apps can be just grabbed from google play. Oh, I removed the stock explorer as well, I use chrome.

I kept huawei music, you should keep this for the screen lock music player and it's widget to function. You do not have to login huawei account to use the music app, it is totally free unless you want SQ or HQ quality songs. All the musics you can listen is free with or without huawei account, as far as I know, this music app is integrated with the biggest chinese music sharing site "cough cough", there could be copyright issues, that's why huawei has blocked login outside China so they don't get into troubles. English or Chinese songs all included in its online data base, although I do find searching in Chinese gives me better results, some english songs are only searchable with their chinese name, (huawei is very dodge here)

For the battery part, I used a combination of paid greenify version, xposed framework, paid wakelock terminator, disable services. And huawei's phone manager, and in the settings, using options of "protected apps" and "startup manager". to minimise everybit of battery drain possible while still keep Gcm and all the important part, like my alarm clock for example. This process is very much depend on each one's own experience and involves a huge amount of common sense plus tweaking and testing. So I can't help you with how exactly you can set this up, but you can search wakelock and greenify guide should give you a start, I greenified almost 60% of my apps including system apps. A few you want to keep them running so your phone functions alright, like the "MMI Function Test" and "MMII test", they appear to be crucial, I disabled them once and find my wifi and data doesn't auto switch, I am sure there might be more to these two apps.

Now for the INSTALLED system app list, pulled from my "system app remover pro" there are 82 in total, this list also includes the ones I pulled from gapps, http://xdaforums.com/showthread.php?t=2397942 I used the "MINI MODULAR PACKAGE", it is possible this remaining list can be further reduced, but I am done for now.
