Mnangagwa, a former deputy president who fell out with Mugabe and then took over from him, urged people to wait for official results. "The strategy is meant to prepare Zim mentally to accept fake presidential results", he tweeted.
"Of the 153, ZANU-PF has won 110 seats, while the MDC Alliance got 41 seats", ZBC state media reported.
Another protester, Colbert Mugwenhi, said: "We had no weapons".
Chamisa's MDC won in most urban centres, where it enjoys majority support.
President Emmerson Mnangagwa of Zimbabwe called for calm on Wednesday as opposition supporters clashed with police in central Harare ahead of the announcement of this week's presidential election results.

Many Zimbabweans looked to the vote as a launching pad for a return to the kind of worldwide acceptance and relative prosperity that the country enjoyed in the first part of the rule of Mugabe, who took office after independence from white minority rule in 1980.
The opposition alleges the elections have irregularities, saying voting results were not posted outside one-fifth of polling stations as required by law.
HARARE, Zimbabwe-The party of former President Robert Mugabe took the majority of seats in Zimbabwe's parliamentary elections, officials said, but European and USA observers expressed reservations about the vote and tensions on the streets of the capital mounted.
The website of the election commission, which is expected to start announcing presidential election results on Thursday, was offline after being taken out by unidentified hackers overnight.

Ellis III offered some humorous encouragement to the jurors chosen for the trial, which is expected to last about three weeks. Manafort's bail was revoked in June while he was on house arrest, after prosecutors accused him of tampering with witnesses.
A Harare-based political analyst with Zimbabwe Democracy Institute, Pedzisai Ruhanya, said the results released so far could be a reflection of the will of the people but were not flawless. "We won the popular vote (and) will defend it", Chamisa said on Twitter.
The election commission, whose website was hacked overnight, said it would announce the results of the vote "very soon" and denied MDC claims that it had allowed ZANU-PF to rig the vote.
Zimbabwe's much-criticised election authority declared that there had been no rigging of the country's election, after the opposition repeatedly alleged that the vote process was flawed.
"For Zimbabwe to embrace democracy and move on from the past, such practices must stop", the team's chief observer, Elmar Brok, said in a statement released Wednesday.
A credible and peaceful vote was meant to end Zimbabwe's global isolation and draw in foreign investment to revive the shattered economy. One independent candidate and a member from a party linked to Mugabe also won one seat each.
They were disputing the results of the National Assembly where ZANU-PF maintained a two thirds majority.
"Rocks were thrown into the compound of the ruling ZANU-PF party".
ZEC is mandated to declare the final results not later than August 4.
Vote counting is still underway to determine the country's next president, a race many analysts predict 75-year-old Mnangagwa will win.
But the opposition says Zanu-PF rigged the election.
