Girls Band Party & New Phone

When the first time BanG Dream Girls Band Party announce the English version is coming in March, I looked up for a new phone candidate. My budget is not much, just uh, 3 million IDR and this will be used for long-term fashion. Here's the criteria I'm looking for:

• Camera doesn't have to be very good, but camera which stabilize when taking photos of text is needed.
• It must comes with at least 64GB of internal storage. Some people says that it's too much, but trust me, having such big storage will come handy in the future.
• Should be recent. 2016 release should be good.
• OS must be Android. Bypassing region lock in Play Store with Android is easier than in iOS, and some of my games are region-locked. The Android version doesn't have to be too new, but Android 7.0 is preferred.
• Must have at least 3GB of RAM. 
• Must have fingerprint sensor (rear-mounted is preferred). I don't want to bash the power button.
• CPU and GPU should be powerful enough. The CPU should be somehow comparable with Intel Atom Z3560. Snapdragon 6xx series chipset looks promising in this case.
• Not to mention screen size. The maximum screen size is 5.5". Bigger than that and I won't able to hold it properly and/or tapping far notes in School Idol Festival.
• Dual-SIM at least.

Inputting those criteria to GSMArena phone finder shows up some result, but decided to filer what I think looks best, and my impression on it:

• SAMSUNG Galaxy S7 and it's variants. People reports playing School Idol Festival with SAMSUNG phone is bad as very old phone. People says the touchscreen is horrible and randomly drops notes, so no for this one. Not to mention it's very expensive.
• OnePlus (any type). Not sure if it's in Indonesia, and I can't find any reports about running School Idol Festival in it. Expensive.
• ASUS ZenFone 3 series. Same as OnePlus above, except it's available in Indonesia, and it's cheaper than OnePlus probably.
• OPPO Series. No idea about running School Idol Festival there. Also it's expensive here and some people says the performance is awful.
• Xiaomi Redmi Note 4. My friend use this one and strongly recommends me this one. It's cheap and suits what I needs, but someone reports playing School Idol Festival there is awful. My friend doesn't recommended the MediaTek version though.
• Motorola Moto X4. Same as OnePlus above.
• ZTE series. Same as OPPO above, but no idea about performance.
• LG G5. I don't know why I put this here. Looks good, but only 32GB of internal storage.
• Motorola Moto G5S+. Looks fit my criteria. I don't like the camera placement (can easily scratched) and the front-mounted fingerprint makes me think twice. Not to mention the audio is horrible according to GSMArena review.
• And the last, Xiaomi Mi A1 (one that I choose; not the 5X variant). Very similar to Moto G5S+ above, and literally someone in SIF Discord confirms the phone to be work with SIF. Doesn't come with Radio FM but it actually has receiver. Cheaper than Moto G5S+ and better, a bit.

(Note that impression above are subjective!)
And then somewhere in early March I got my Mi A1. Testing time.

School Idol Festival runs fine. No stutters. No lags. Performs exactly same as my previous phone, ASUS ZenFone 2 (which uses Intel Atom Z3560). Testing the Japanese version of Girls Band Party, unfortunately lags out when doing Live! and when reading some stories (probably there are too many Live2D objects to load and render). My older ZenFone 2 still performs way better, probably because Girls Band Party is way more optimized in x86 platform than ARM. But since v2.0.0 of the game, the lag is significantly minimal now. Only lags a bit when doing multi live with LIVE FEVER (all effects enabled). Not sure how my ZenFone 2 handles v2.0.0 now, probably without any lag at all.

Battery life is good. You know what, the first time I extensively testing this phone is by playing SIF and reaching the top 1100. Long run test (2 hours) for reaching 25k event points only consume 20% of battery, which is I can consider very good, although not as good as Redmi Note 4's 4100mAh battery, but I can say it's acceptable.

For the Global version of Girls Band Party, surprisingly, less laggy than pre-v2.0.0 Japanese version of the game. In math, the lagness will be notated as "v2.0.0 JP < v1.1 WW < pre-v2.0.0 JP" where v2.0.0 JP is the most less lag.

To end this up, Girls Band Party performs better in x86 phones (BLACK SHOUTsly ZenFone 2), but x86 phones are horrible in terms of battery life, and it gets really hot in short time.
